On one of my test machines nhi_mailbox_cmd() called from icm_suspend()
times out and returnes an error which then is propagated to the
caller and causes the entire system suspend to be aborted which isn't
very useful.
Instead of aborting system suspend, print the error into the log
and continue.

This patch drops two incorrect usages of tcm_qla2xxx_free_cmd()
during TMR ABORT within tcm_qla2xxx_handle_data_work() and
tcm_qla2xxx_aborted_task(), which where attempting to dispatch
into workqueue context to do tcm_qla2xxx_complete_free() and
subsequently invoke transport_generic_free_cmd().
This is incorrect because during TMR ABORT target-core will
drop the outstanding se_cmd->cmd_kref references once it has
quiesced the se_cmd via transport_wait_for_tasks(), and in
the case of qla2xxx it should not attempt to do it's own
transport_generic_free_cmd() once the abort has occured.
As reported by Pascal, this was originally manifesting as a
BUG_ON(cmd->cmd_in_wq) in qlt_free_cmd() during TMR ABORT,
with a LIO backend that had sufficently high enough WRITE
latency to trigger a host side TMR ABORT_TASK.
(v2: Drop the qla_tgt_cmd->write_pending_abort_comp changes,
as they will be addressed in a seperate series)

The current logic of calculating sg_nents can fail
if data_offset % PAGE_SIZE is not zero.
For example -
PAGE_SIZE = 4096
data_len = 3072
data_offset = 3072
As per current logic
sg_nents = max(1UL, DIV_ROUND_UP(data_len, PAGE_SIZE));
sg_nents = max(1UL, DIV_ROUND_UP(3072, 4096));
sg_nents = 1
But as data_offset % PAGE_SIZE = 3072 we should skip 3072 bytes
skip = 3K
sg_nents = max(1UL, DIV_ROUND_UP(3K(skip) + 3K(data_len), 4K(PAGE_SIZE));
sg_nents = 2;
This patch fixes this issue by adding skip to data_len.

On receiving text request iscsi-target allocates buffer for
payload in iscsit_handle_text_cmd() and assigns buffer pointer
to cmd->text_in_ptr, this buffer is currently freed in
iscsit_release_cmd(), if iscsi-target sets 'C' bit in text
response then it will receive another text request from the
initiator with ttt != 0xffffffff in this case iscsi-target
will find cmd using itt and call iscsit_setup_text_cmd()
which will set cmd->text_in_ptr to NULL without freeing
previously allocated buffer.
This patch fixes this issue by calling kfree(cmd->text_in_ptr)
in iscsit_setup_text_cmd() before assigning NULL to it.
For the first text request cmd->text_in_ptr is NULL as
cmd is memset to 0 in iscsit_allocate_cmd().

ADC clock input is provided to internal prescaler (that decreases its
frequency). It's then used as reference clock for conversions.
- Fix common clock rate used then by stm32-adc sub-devices. Take common
prescaler into account. Currently, rate is used to set "boost" mode.
It may unnecessarily be set. This impacts power consumption.
- Fix ADC max clock rate on STM32H7 (fADC from datasheet). Currently,
prescaler may be set too low. This can result in ADC reference
clock used for conversion to exceed max allowed clock frequency.

Comedi's read and write file operation handlers (`comedi_read()` and

whilst in the `TASK_INTERRUPTIBLE` state, which falls foul of the

The work-around for Qualcomm Technologies QDF2400 Erratum 44 hinges on a
global variable defined in the pl011 driver. The ACPI SPCR parsing code
determines whether the work-around is needed, and if so, it changes the
console name from "pl011" to "qdf2400_e44". The expectation is that
the pl011 driver will implement the work-around when it sees the console
name. The global variable qdf2400_e44_present is set when that happens.
The problem is that work-around needs to be enabled when the pl011
driver probes, not when the console name is queried. However, sbsa_probe()
is called before pl011_console_match(). The work-around appeared to work
previously because the default console on QDF2400 platforms was always
ttyAMA1. The first time sbsa_probe() is called (for ttyAMA0),
qdf2400_e44_present is still false. Then pl011_console_match() is called,
and it sets qdf2400_e44_present to true. All subsequent calls to
sbsa_probe() enable the work-around.
The solution is to move the global variable into spcr.c and let the
pl011 driver query it during probe time. This works because all QDF2400
platforms require SPCR, so parse_spcr() will always be called.
pl011_console_match still checks for the "qdf2400_e44" console name,
but it doesn't do anything else special.
Fixes: 5a0722b898f8 ("tty: pl011: use "qdf2400_e44" as the earlycon name for QDF2400 E44")

commit 68fe05e2a451 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.
So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.
Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.
This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

Christoph Hellwig says that since version 4.12, the kernel switched to
using blk-mq by default. The old code used a softirq for handling
request completions, but blk-mq can handle completions in the caller's
context. This may cause a problem for usb-storage, because it invokes
the ->scsi_done callback while holding the host lock, and the
completion routine sometimes tries to acquire the same lock (when
running the error handler, for example).
The consequence is that the existing code will sometimes deadlock upon
error completion of a SCSI command (with a lockdep warning).
This is easy enough to fix, since usb-storage doesn't really need to
hold the host lock while the callback runs. It was simpler to write
it that way, but moving the call outside the locked region is pretty
easy and there's no downside. That's what this patch does.

Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared
HCD and set HCD_FLAG_DEAD for it, in analogy with what is done for
the primary one.
Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.
This actually fixes occasional suspend failures on one of my test
machines.

Proper support for the INA219 lowered the minimum sampling period from
2*140us to 2*84us. Subtracting 200us later leads to an underflow and
an almost infinite udelay later.
Using a signed int for the sampling period provides sufficient range
(at most 2*8640*1024us), but catches the underflow when comparing with
buffer_us.

If the device is not initialized at least once it happens that the humidity
reading is skipped, which means the special value 0x8000 is delivered.
For omitting this case the oversampling of the humidity must be set before
the oversampling of the temperature und pressure is set as written in the
datasheet of the BME280.
Furthermore proper error detection is added in case a skipped value is read
from the device. This is done also for pressure and temperature reading.
Especially it don't make sense to compensate this value and treat it as
regular value.

"Here are a couple of mmc fixes intended for v4.13-rc1.
I have also included a couple of cleanup patches in this pull request
for OMAP2+, related to the omap_hsmmc driver. The reason is because of
the changes are also depending on OMAP SoC specific code, so this
simplifies how to deal with this.

When a lba either hits the cache or corresponds to an empty entry in the
L2P table, we need to advance the bio according to the position in which
the lba is located. Otherwise, we will copy data in the wrong page, thus
causing data corruption for the application.
In case of a cache hit, we assumed that bio->bi_iter.bi_idx would
contain the correct index, but this is no necessarily true. Instead, use
the local bio advance counter and iterator. This guarantees that lbas
hitting the cache are copied into the right bv_page.
In case of an empty L2P entry, we omitted to advance the bio. In the
cases when the same I/O also contains a cache hit, data corresponding
to this lba will be copied to the wrong bv_page. Fix this by advancing
the bio as we do in the case of a cache hit.

The output node of the TC358767 is only used if another bridge is chained
behind it. Panels attached to the TC358767 can be detected using the usual
DP AUX probing. This restores the old behavior of ignoring the output if
no endpoint is found.

Pull drm fixes from Dave Airlie:
"These iare the fixes for 4.13-rc3: vmwgfx, exynos, i915, amdgpu,
nouveau, host1x and displayport fixes.
As expected people woke up this week, i915 didn't do an -rc2 pull so
got a bumper -rc3 pull, and Ben resurfaced on nouveau and fixed a
bunch of major crashers seen on Fedora 26, and there are a few vmwgfx

The driver attempts to 'select MDIO_DEVICE', but the code

phy-bcm-ns-usb3.c:(.text.bcm_ns_usb3_mdiodev_phy_write+0x28): undefined reference to `mdiobus_write'

I still see build errors in randconfig builds and have had this
patch for a while to locally work around it:
drivers/built-in.o: In function `xgene_mdio_probe':
mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register'
mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free'
mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size'
The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus
code is built-in or a module, and other drivers that use the core
code can simply depend on that, instead of having a complex
dependency line.

Pull ACPI fixes from Rafael Wysocki:
"These are two fixups for the suspend-to-idle handling in the ACPI
subsystem after recent changes in that area and two simple fixes of
the ACPI NUMA code.
Specifics:
- Add an ACPI module parameter to allow users to override the new
default behavior on some systems where the EC GPE is not disabled
during suspend-to-idle in case the EC on their systems generates
excessive wakeup events and they want to sacrifice some
functionality (like power button wakeups) for extra battery life
while suspended (Rafael Wysocki).
- Fix flushing of the outstanding EC work in the ACPI core
suspend-to-idle code (Rafael Wysocki).
- Add a missing include and fix a messed-up comment in the ACPI NUMA
code (Ross Zwisler)"

The ->get callback in the intel_pstate structure was mostly there
for the scaling_cur_freq sysfs attribute to work, but after commit
f8475cef9008 (x86: use common aperfmperf_khz_on_cpu() to calculate
KHz using APERF/MPERF) that attribute uses arch_freq_get_on_cpu()
provided by the x86 arch code on all processors supported by
intel_pstate, so it doesn't need the ->get callback from the
driver any more.
Moreover, the very presence of the ->get callback in the intel_pstate
structure causes the cpuinfo_cur_freq attribute to be present when
intel_pstate operates in the active mode, which is bogus, because
the role of that attribute is to return the current CPU frequency
as seen by the hardware. For intel_pstate, though, this is just an
average frequency and not really current, but computed for the
previous sampling interval (the actual current frequency may be
way different at the point this value is obtained by reading from
cpuinfo_cur_freq), and after commit 82b4e03e01bc (intel_pstate: skip
scheduler hook when in "performance" mode) the value in
cpuinfo_cur_freq may be stale or just 0, depending on the driver's
operation mode. In fact, however, on the hardware supported by
intel_pstate there is no way to read the current CPU frequency
from it, so the cpuinfo_cur_freq attribute should not be present
at all when this driver is in use.
For this reason, drop intel_pstate_get() and clear the ->get
callback pointer pointing to it, so that the cpuinfo_cur_freq is
not present for intel_pstate in the active mode any more.
