[ Upstream commit 07922937e9a580825f9965c46fd15e23ba5754b6 ]
hdpvr_register_videodev is responsible to initialize a worker in
hdpvr_device. However, the worker is only initialized at
hdpvr_start_streaming other than hdpvr_register_videodev.
When hdpvr_probe does not initialize its worker, the hdpvr_disconnect
will encounter one WARN in flush_work.The stack trace is as follows:
hdpvr_disconnect+0xb8/0xf2 drivers/media/usb/hdpvr/hdpvr-core.c:425
usb_unbind_interface+0xbf/0x3a0 drivers/usb/core/driver.c:458

Fix this by moving the initialization of dev->worker to the starting of
hdpvr_register_videodev

[ Upstream commit fde18c3bac3f964d8333ae53b304d8fee430502b ]
This reverts commit 2c98b8a3458df03abdc6945bbef67ef91d181938.
Reverted patch causes problems with Hauppauge WinTV dualHD as Maximilian
reported [1]. Since quick solution didn't come up let's just revert it
to make this device work with upstream kernels.

[ Upstream commit d4cb5d3c4cee28aa89b02bc33d930a6cf75e7f79 ]
ov5648_state_init() calls ov5648_state_mipi_configure() which uses
__v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which
is also sensor->ctrls.handler.lock) must be locked before calling
ov5648_state_init().
ov5648_state_mipi_configure() is also used in other places where
the lock is already held so it cannot be changed itself.
Note this is based on an identical (tested) fix for the ov8865 driver,
this has only been compile-tested.

Make sure in .probe() to set driver data before the function is left to
make it possible in .remove() to undo the actions done.
This fixes a potential memory leak and stops returning an error code in

[ Upstream commit 5a06fcb15b43d1f7bf740c672950122331cb5655 ]
test_kernel_ptr() uses access_ok() to figure out if a given address
points to user space instead of kernel space. However on architectures
that set CONFIG_ALTERNATE_USER_ADDRESS_SPACE, a pointer can be valid
for both, and the check always fails because access_ok() returns true.
Make the check for user space pointers conditional on the type of
address space layout.

[ Upstream commit 97558d170a1236280407e8d29a7d095d2c2ed554 ]
When error occurs in parsing jpeg, the slot isn't acquired yet, it may
be the default value MXC_MAX_SLOTS.
If the driver access the slot using the incorrect slot number, it will
access array out of bounds.
The result is the driver will change num_domains, which follows
slot_data in struct mxc_jpeg_dev.
Then the driver won't detach the pm domain at rmmod, which will lead to
kernel panic when trying to insmod again.

[ Upstream commit f7d344a2bd5ec81fbd1ce76928fd059e57ec9bea ]
In the case like dmaengine which's not a dai but as a component, the
num_dai is zero, dmaengine component has the same component_of_node
as cpu dai, when cpu dai component is not ready, but dmaengine component
is ready, try to get cpu dai name, the snd_soc_get_dai_name() return
-EINVAL, not -EPROBE_DEFER, that cause below error:
asoc-simple-card <card name>: parse error -22
asoc-simple-card: probe of <card name> failed with error -22
The sound card failed to probe.
So this patch fixes the issue above by skipping the zero num_dai
component in searching dai name.

Tweak the ftrace return paths to avoid redundant loads of SP, as well as
unnecessary clobbering of IP.
This also fixes the inconsistency of using MOV to perform a function
return, which is sub-optimal on recent micro-architectures but more
importantly, does not perform an interworking return, unlike compiler
generated function returns in Thumb2 builds.
Let's fix this by popping PC from the stack like most ordinary code

The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.
At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.
So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.

The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

Do a sanity check on pixclock value to avoid divide by zero.
If the pixclock value is zero, the cirrusfb driver will round up
pixclock to get the derived frequency as close to maxclock as

w100fb_probe() did not reset the global state to its initial state. This
can result in invocation of iounmap() even when there was not the
appropriate successful call of ioremap(). For instance, this may be the
case if first probe fails after two successful ioremap() while second
probe fails when first ioremap() fails. The similar issue is with
w100fb_remove(). The patch fixes both bugs.

[ Upstream commit 37a1a2e6eeeb101285cd34e12e48a881524701aa ]
Coverity complains of a possible buffer overflow. However,
given the 'static' scope of nvidia_setup_i2c_bus() it looks
like that can't happen after examiniing the call sites.
CID 19036 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)
1. fixed_size_dest: You might overrun the 48-character fixed-size string
chan->adapter.name by copying name without checking the length.
2. parameter_as_source: Note: This defect has an elevated risk because the
source argument is a parameter of the current function.
89 strcpy(chan->adapter.name, name);
Fix this warning by using strscpy() which will silence the warning and
prevent any future buffer overflows should the names used to identify the
channel become much longer.

[ Upstream commit 635319a4a7444ca97124d781cd96deb277ff4d40 ]
MediaTek IOMMU-SMI diagram is like below. all the consumer connect with
smi-larb, then connect with smi-common.
M4U
|
smi-common
|
-------------
| | ...
| |
larb1 larb2
| |
vdec venc
When the consumer works, it should enable the smi-larb's power which
also need enable the smi-common's power firstly.
Thus, First of all, use the device link connect the consumer and the
smi-larbs. then add device link between the smi-larb and smi-common.
This patch adds device_link between the consumer and the larbs.
When device_link_add, I add the flag DL_FLAG_STATELESS to avoid calling
pm_runtime_xx to keep the original status of clocks. It can avoid two
issues:
1) Display HW show fastlogo abnormally reported in [1]. At the beggining,
all the clocks are enabled before entering kernel, but the clocks for
display HW(always in larb0) will be gated after clk_enable and clk_disable
called from device_link_add(->pm_runtime_resume) and rpm_idle. The clock
operation happened before display driver probe. At that time, the display
HW will be abnormal.
2) A deadlock issue reported in [2]. Use DL_FLAG_STATELESS to skip
pm_runtime_xx to avoid the deadlock.
Corresponding, DL_FLAG_AUTOREMOVE_CONSUMER can't be added, then
device_link_removed should be added explicitly.
Meanwhile, Currently we don't have a device connect with 2 larbs at the
same time. Disallow this case, print the error log.

[ Upstream commit 822a2ed8c606caf6a11b1a180b8e46292bd77d71 ]
When the iommu master device enters of_iommu_xlate, the ops may be
NULL(iommu dev is defered), then it will initialize the fwspec here:
[<c0c9c5bc>] (dev_iommu_fwspec_set) from [<c06bda80>]
(iommu_fwspec_init+0xbc/0xd4)
[<c06bd9c4>] (iommu_fwspec_init) from [<c06c0db4>]

[<c06c0d38>] (of_iommu_xlate) from [<c06c10e8>]
(of_iommu_configure+0x144/0x1e8)
BUT the mtk_iommu_v1.c only supports arm32, the probing flow still is a bit
weird. We always expect create the fwspec internally. otherwise it will
enter here and return fail.
static int mtk_iommu_create_mapping(struct device *dev,
struct of_phandle_args *args)
{
...
if (!fwspec) {
....
} else if (dev_iommu_fwspec_get(dev)->ops != &mtk_iommu_ops) {
>>>>>>>>>>Enter here. return fail.<<<<<<<<<<<<
return -EINVAL;
}
...
}
Thus, Free the existed fwspec if the master device already has fwspec.

The ISC supports a full broad range of frame sizes.
Until now, the subdevice was queried for possible frame sizes and these
were reported to the user space.
However, the ISC should not care about which frame sizes the subdev
supports, as long as this frame size is supported.
Thus, report a continuous range from smallest frame size up to the max
resolution.

We can either fail to find a csum entry at all and return -ENOENT, or we
can find a range that is close, but return -EFBIG. In essence these
both mean the same thing when we are doing a lookup for a csum in an
existing range, we didn't find a csum. We want to treat both of these
errors the same way, complain loudly that there wasn't a csum. This
currently happens anyway because we do
count = search_csum_tree();
if (count <= 0) {
// reloc and error handling
}
However it forces us to incorrectly treat EIO or ENOMEM errors as on
disk corruption. Fix this by returning 0 if we get either -ENOENT or
-EFBIG from btrfs_lookup_csum() so we can do proper error handling.

[ Upstream commit 770c79fb65506fc7c16459855c3839429f46cb32 ]
Identifying and removing the stale device from the fs_uuids list is done
by btrfs_free_stale_devices(). btrfs_free_stale_devices() in turn
depends on device_path_matched() to check if the device appears in more
than one btrfs_device structure.
The matching of the device happens by its path, the device path. However,
when device mapper is in use, the dm device paths are nothing but a link
to the actual block device, which leads to the device_path_matched()
failing to match.
Fix this by matching the dev_t as provided by lookup_bdev() instead of
plain string compare of the device paths.

These have been incorrect since the function was introduced.
A proper kerneldoc comment is added since this function, though
static, is part of an external interface.

The root cause is we missed to do sanity check on curseg->alloc_type,
result in out-of-bound accessing on sbi->block_count[] array, fix it.

[ Upstream commit cc5095747edfb054ca2068d01af20be3fcc3634f ]
[un]pin_user_pages_remote is dirtying pages without properly warning
the file system in advance. A related race was noted by Jan Kara in
2018[1]; however, more recently instead of it being a very hard-to-hit
race, it could be reliably triggered by process_vm_writev(2) which was
discovered by Syzbot[2].
This is technically a bug in mm/gup.c, but arguably ext4 is fragile in
that if some other kernel subsystem dirty pages without properly
notifying the file system using page_mkwrite(), ext4 will BUG, while
other file systems will not BUG (although data will still be lost).
So instead of crashing with a BUG, issue a warning (since there may be
potential data loss) and just mark the page as clean to avoid
unprivileged denial of service attacks until the problem can be
properly fixed. More discussion and background can be found in the
thread starting at [2].
