commit a8002a35935aaefcd6a42ad3289f62bab947f2ca upstream.
If no n_latch value will be provided at driver probe then all pins will
be used as an input:
gpio->out = ~n_latch;
In that case initial state for all pins is "one":
gpio->status = gpio->out;
So if pcf857x IRQ happens with change pin value from "zero" to "one"
then we miss it, because of "one" from IRQ and "one" from initial state
leaves corresponding pin unchanged:
change = (gpio->status ^ status) & gpio->irq_enabled;
The right solution will be to read actual state at driver probe.

commit a56f44138a2c57047f1ea94ea121af31c595132b upstream.
In sdhci_esdhc_imx_remove() the SDHCI_INT_STATUS in read. Under some
circumstances, this may be done while the device is runtime suspended,
triggering the below splat.
Fix the problem by adding a pm_runtime_get_sync(), before reading the
register, which will turn on clocks etc making the device accessible again.

commit 8a0c014cd20516ade9654fc13b51345ec58e7be8 upstream.
This issue was originally fixed in 09954bad4 ("floppy: refactor open()
flags handling").
The fix as a side-effect, however, introduce issue for open(O_ACCMODE)
that is being used for ioctl-only open. I wrote a fix for that, but
instead of it being merged, full revert of 09954bad4 was performed,
re-introducing the O_NDELAY / O_NONBLOCK issue, and it strikes again.
This is a forward-port of the original fix to current codebase; the
original submission had the changelog below:
====
Commit 09954bad4 ("floppy: refactor open() flags handling"), as a
side-effect, causes open(/dev/fdX, O_ACCMODE) to fail. It turns out that
this is being used setfdprm userspace for ioctl-only open().
Reintroduce back the original behavior wrt !(FMODE_READ|FMODE_WRITE)
modes, while still keeping the original O_NDELAY bug fixed.

commit 4b049f55ed95cd889bcdb3034fd75e1f01852b38 upstream.
The dep->interval captures the number of frames/microframes per interval
from bInterval. Fullspeed interrupt endpoint bInterval is the number of
frames per interval and not 2^(bInterval - 1). So fix it here. This
change is only for debugging purpose and should not affect the interrupt
endpoint operation.

commit 0eaa1a3714db34a59ce121de5733c3909c529463 upstream.
musb_queue_resume_work() would call the provided callback if the runtime
PM status was 'active'. Otherwise, it would enqueue the request if the
hardware was still suspended (musb->is_runtime_suspended is true).
This causes a race with the runtime PM handlers, as it is possible to be
in the case where the runtime PM status is not yet 'active', but the
hardware has been awaken (PM resume function has been called).
When hitting the race, the resume work was not enqueued, which probably
triggered other bugs further down the stack. For instance, a telnet
connection on Ingenic SoCs would result in a 50/50 chance of a
segmentation fault somewhere in the musb code.
Rework the code so that either we call the callback directly if
(musb->is_runtime_suspended == 0), or enqueue the query otherwise.

commit 6420a569504e212d618d4a4736e2c59ed80a8478 upstream.
This patch prepares for qmi_wwan driver support for the device.
Previously "option" driver mapped itself to interfaces 0 and 3 (matching
ff/ff/ff), while interface 3 is in fact a QMI port.
Interfaces 1 and 2 (matching ff/00/00) expose AT commands,
and weren't supported previously at all.
Without this patch, a possible conflict would exist if device ID was
added to qmi_wwan driver for interface 3.
Update and simplify device ID to match interfaces 0-2 directly,
to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict
with QMI (3), and ADB (4).
The modem is used inside ZTE MF283+ router and carriers identify it as
such.
Interface mapping is:

commit b5d6e7ab7fe7d186878142e9fc1a05e4c3b65eb9 upstream.
After commit 77b425399f6d ("Input: i8042 - use chassis info to skip
selftest on Asus laptops"), all modern Asus laptops have the i8042
selftest disabled. It has done by using chassys type "10" (laptop).
The Asus Zenbook Flip suffers from similar suspend/resume issues, but
it _sometimes_ work and sometimes it doesn't. Setting noselftest makes
it work reliably. In this case, we need to add chassis type "31"
(convertible) in order to avoid selftest in this device.

[ Upstream commit 92c6058024e87087cf1b99b0389d67c0a886360e ]
When a packet contains an IPv6 header with next header which is
an extension header and not a protocol one, the kernel function
skb_transport_header called with such sk_buff will return a
pointer to the extension header and not to the TCP one.
The above explained call caused a problem with packet processing
for skb with encapsulation for tunnel with I40E_TX_CTX_EXT_IP_IPV6.
The extension header was not skipped at all.
The ipv6_skip_exthdr function does check if next header of the IPV6
header is an extension header and doesn't modify the l4_proto pointer
if it points to a protocol header value so its safe to omit the
comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can
return value -1. This means that the skipping process failed
and there is something wrong with the packet so it will be dropped.

being unprepared when it is still enabled, and then being unprepared when
it has already been unprepared.

[ Upstream commit de5d7adb89367bbc87b4e5ce7afe7ae9bd86dc12 ]
Consider an amba driver with a .probe but without a .remove callback (e.g.
pl061_gpio_driver). The function amba_probe() is called to bind a device
and so dev_pm_domain_attach() and others are called. As there is no remove
callback amba_remove() isn't called at unbind time however and so calling
dev_pm_domain_detach() is missed and the pm domain keeps active.
To fix this always use the core driver callbacks and handle missing amba
callbacks there. For probe refuse registration as a driver without probe
doesn't make sense.

[ Upstream commit 8a5a75e5e9e55de1cef5d83ca3589cb4899193ef ]
If the device tree is incorrectly configured, and attempts to
define a "no-map" reserved memory that overlaps with the kernel
data/code, the kernel would crash quickly after boot, with no
obvious clue about the nature of the issue.
For example, this would happen if we have the kernel mapped at
these addresses (from /proc/iomem):
40000000-41ffffff : System RAM
40080000-40dfffff : Kernel code
40e00000-411fffff : reserved
41200000-413e0fff : Kernel data
And we declare a no-map shared-dma-pool region at a fixed address
within that range:
mem_reserved: mem_region {
compatible = "shared-dma-pool";
reg = <0 0x40000000 0 0x01A00000>;
no-map;
};
To fix this, when removing memory regions at early boot (which is
what "no-map" regions do), we need to make sure that the memory
is not already reserved. If we do, __reserved_mem_reserve_reg
will throw an error:
[ 0.000000] OF: fdt: Reserved memory: failed to reserve memory
for node 'mem_region': base 0x0000000040000000, size 26 MiB
and the code that will try to use the region should also fail,
later on.
We do not do anything for non-"no-map" regions, as memblock
explicitly allows reserved regions to overlap, and the commit
that this fixes removed the check for that precise reason.

[ Upstream commit ceeda328edeeeeac7579e9dbf0610785a3b83d39 ]
The controller can only support up to 31 dummy cycles. If the command
requires more it falls back to using 31. This command is likely to fail
because the correct number of cycles are not waited upon. Rather than
silently issuing an incorrect command, fail loudly so the caller can get
a chance to find out the command can't be supported by the controller.

[ Upstream commit 2f290b7c67adf6459a17a4c978102af35cd62e4a ]
The "rate" parameter in meson_clk_pll_set_rate() contains the new rate.
Retrieve the old rate with clk_hw_get_rate() so we don't inifinitely try
to switch from the new rate to the same rate again.

[ Upstream commit 10340f8d7b6dd54e616339c8ccb2f397133ebea0 ]
While reworking the resources management and departing from using
ahci_platform_enable_resources() which did not allow a proper step
separation like we need, we unfortunately lost the ability to control
AHCI regulators. This broke some Broadcom STB systems that do expect
regulators to be turned on to link up with attached hard drives.

[ Upstream commit dc9455ffae02d7b7fb51ba1e007fffcb9dc5d890 ]
The Renkforce RF AC4K 300 Action Cam 4K reports invalid bFormatIndex and
bFrameIndex values when negotiating the video probe and commit controls.
The UVC descriptors report a single supported format and frame size,
with bFormatIndex and bFrameIndex both equal to 2, but the video probe
and commit controls report bFormatIndex and bFrameIndex set to 1.
The device otherwise operates correctly, but the driver rejects the
values and fails the format try operation. Fix it by ignoring the
invalid indices, and assuming that the format and frame requested by the
driver are accepted by the device.

[ Upstream commit b2de3643c5024fc4fd128ba7767c7fb8b714bea7 ]
This function looks like a realloc.
However, if 'risc->cpu != NULL', the memory will be freed, but never
reallocated with the bigger 'size'.
Explicitly set 'risc->cpu' to NULL, so that the reallocation is
correctly performed a few lines below.
