The variable result is being initialized with a value that is never
read and it is being updated later with a new value. The initialization
is redundant and can be removed.

Currently, the CSI2 subdevice is using the data-lanes from the
neareast endpoint to config the CSI2 lanes.
While this may work, the proper way to configure the hardware is
to obtain the remote subdevice in v4l2_async_notifier_operations.bound(),
and then call get_mbus_config using the remote subdevice to get
the active lanes.

According to v4l2 request api specifications, it's allowed to skip
control if its content isn't changed for performance reasons. Cedrus
driver predates that, so it has implemented mechanism to check if all
required controls are included in one request.
Conform to specifications with removing that mechanism.
Note that this mechanism with static required flag isn't very good
anyway because need for control is usually signaled in other controls.

During H264 API overhaul subtle bug was introduced Cedrus driver.
Progressive references have both, top and bottom reference flags set.
Cedrus reference list expects only bottom reference flag and only when
interlaced frames are decoded. However, due to a bug in Cedrus check,
exclusivity is not tested and that flag is set also for progressive
references. That causes "jumpy" background with many videos.
Fix that by checking that only bottom reference flag is set in control
and nothing else.

During the driver refactor, a regression broke the logic inside
hi6421_spmi_regulator_get_optimum_mode(). Basically, if a LDO
has eco_uA == 0, it doesn't support economic mode. So, it should
return REGULATOR_MODE_NORMAL.
If economic mode is supported, it can return either
REGULATOR_MODE_IDLE or REGULATOR_MODE_NORMAL, depending on the
load current.

The original driver, which can be seen at
commit 42f24d9d446a ("staging: regulator: add a regulator driver for HiSilicon 6421v600 SPMI PMIC")
had a complex logic to ensure that there won't be multiple power
enable/disable commands running at the same time. At the original
logic, it were ensured that:
- a next power up/down would wait for at least the on/off period;
- an extra delay would be granted. It turns that such extra delay
has a value of zero, but it was relying on gettimeofday()
call, which can take some time.
This was later simplified, but there are still some possible
issues. In order to avoid that, let's simply add a delay
to wait for the power up line to stabilize after powering up
a device.

The interrupt support for Advantech PCI-1730 currrently supports only
rising edge inputs for the trigger sources. Each of four interrupt
sources (each with its own Comedi subdevice) can be set to trigger on
either a rising edge or a falling edge. Add support for choosing the
edge during set-up of the asynchronous command for the subdevice, using
the `CR_INVERT` bit of `scan_begin_arg` to indicate falling edge when
set, or rising edge when clear. Also allow the `CR_EDGE` bit to be set,
but ignore it. All other bits of `scan_begin_arg` must be zero.

On the Advantech PCI-1730, four digital inputs (DI0, DI1, IDI0 and IDI1)
can be used as external interrupt sources. Each input can be programmed
to latch an interrupt bit on either a rising edge or a falling edge (but
not both).
Add a new Comedi subdevice for each interrupt source, supporting the
asynchronous command interface. Subdevices 5, 6, 7 and 8 are for
interrupt sources DI0, DI1, IDI0 and IDI1. They each write the state of
16 digital inputs to the subdevice's data buffer each time the
corresponding interrupt occurs. (For DI0 and DI1, use the 16
non-isolated digital inputs. For IDI0 and IDI1, use the 16 isolated
digital inputs.)
Currently, only rising edge triggers are supported. Support could be
added for the PCI-1733 and PCI-1736.

On the ADLink PCI-7230, digital input channels 0 and 1 can be used as
external interrupt sources. A rising edge on each input latches a
corresponding local interrupt input of the PCI interface chip. Writing
a "clear IRQ" register clears both latches.
Add a new Comedi subdevice for each interrupt source, supporting the
asynchronous command interface. This writes the state of the 16 digital
inputs to the subdevice's data buffer each time the corresponding
interrupt occurs.
This could be adapted to support the PCI-7233, PCI-7432 and PCI-7433
boards too. They all have two interrupt sources, although for PCI-7233
each interrupt source is triggered by a change of state of 16 digital
inputs (0-15 and 16-31). The "clear IRQ" register is at a different
offset for some boards.

The custom regulatory ruleset in the rtl8723bs driver lists an incorrect
number of rules: one too many. This results in an out-of-bounds access,
as detected by KASAN. This was possible thanks to the newly added support
for KASAN on ARMv7.
Fix this by filling in the correct number of rules given.

This code ends up calling wiphy_apply_custom_regulatory(), for which
we document that it should be called before wiphy_register(). This
driver doesn't do that, but calls it from ndo_open() with the RTNL
held, which caused deadlocks.
Since the driver just registers static regdomain data and then the
notifier applies the channel changes if any, there's no reason for
it to call this in ndo_open(), move it earlier to fix the deadlock.

We can not make the assumption that the bound subdev is always a CSI
mux, in i.MX6UL/i.MX6ULL that is not the case. So, just get the entity
selected by source directly upstream from the CSI.

Commit 86e02d07871c ("media: imx5/6/7: csi: Mark a bound video mux as
a CSI mux") made an incorrect assumption that for imx7-media-csi,
the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there
is no CSI mux at all, so do not return an error when the entity is not a
video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when
appropriate.
This is the same approach as done in imx-media-csi.c and it fixes the
csi probe regression on i.MX6UL.
Tested on a imx6ull-evk board.

Remove MODULE_VERSION(), as it doesn't seem to serve any practical purpose.
For in-tree drivers, the kernel version matters. The code received lots of
changes, but module version remained constant, since the driver landed in
mainline. So, this version doesn't seem have any practical meaning anymore.

No locking is needed to call video_unregister_device(). Drop it.
Also, drop the superfluous video_is_registered() call, which is
done by video_unregister_device(), and re-order media_entity_cleanup()

The csc/scaler device private struct is released by
ipu_csc_scaler_video_device_release(), which can be called
by video_unregister_device() if there are no users
of the underlying struct video device.
Therefore, the mutex can't be held when calling
video_unregister_device() as its memory may be freed
by it, leading to a kernel oops.
Fortunately, the fix is quite simple as no locking
is needed when calling video_unregister_device(): v4l2-core
already has its own internal locking, and the structures
are also properly refcounted.

The csc/scaler device pointer (imxmd->m2m_vdev) is assigned
after the imx media device v4l2-async probe completes,
therefore we need to check if the device is non-NULL
before trying to unregister it.
This can be the case if the non-completed imx media device
is unbinded (or the driver is removed), leading to a kernel oops.
