"card" is a valid pointer here because we checked snd_card_create() for
error returns.  Checking after a dereference makes the static checkers

a7bd775628 [media] mem2mem_testdev: unlock and return error code properly
We recently added locking to this function, but there was an error path
which accidentally returned holding a lock.  Also we returned zero on
failure on some paths instead of the error code.

5359805193 [media] it913x-fe: use ARRAY_SIZE() as a cleanup
This code looks suspicious, but it turns out that "nv" is an array of u8
so sizeof() is the same as ARRAY_SIZE().  Using ARRAY_SIZE() is more
readable though.

4bbc6d52e6 [media] soc-camera: Push probe-time power management to drivers
Several client drivers access the hardware at probe time, for instance
to read the probe chip ID. Such chips need to be powered up when being
probed.

soc-camera handles this by powering chips up in the soc-camera probe
implementation. However, this will break with non soc-camera hosts that
don't perform the same operations.

Fix the problem by pushing the power up/down from the soc-camera core
down to individual drivers on a needs basis.

Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.

24592adce8 [media] soc-camera: Continue the power off sequence if one of the steps fails
Powering off a device is a "best effort" task: failure to execute one of
the steps should not prevent the next steps to be executed. For
instance, an I2C communication error when putting the chip in stand-by
mode should not prevent the more agressive next step of turning the
chip's power supply off.
