Using the ARRAY_SIZE macro improves the readability of the code. Also,
it is not always useful to use a variable to store this constant
calculated at compile time.

Use a more typical logging style.
The current macro hides the gspca_dev argument so add it to the
macro uses instead.
Miscellanea:
o Add missing '\n' terminations to formats
o Realign arguments to open parenthesis
o Remove commented out uses of PDEBUG

Here, hdpvr_register_videodev() is responsible for setup and
register a video device. Also defining and initializing a worker.
hdpvr_register_videodev() is calling by hdpvr_probe at last.
So no need to flush any work here.
Unregister v4l2, free buffers and memory. If hdpvr_probe() will fail.

The current implementation has to search the list of controls for the
pixel rate control, each time it is set. This can be optimised easily
by storing the ctrl pointer in the CSI/TX object, and referencing that
directly.
While at it, fix up a missing blank line also highlighted in review
comments.

When matching and registering a sub-device from a sub-notifier use the
v4l2_device from the root parent notifier. Using the v4l2_dev stored in
the sub-notifier itself is incorrect as it might not be set.
This can be demonstrated by unbinding and rebinding the adv748x driver
and observing that it fails to probe due to the check !v4l2_dev in
v4l2_device_register_subdev().
# echo 4-0070 > /sys/bus/i2c/drivers/adv748x/unbind
# echo 4-0070 > /sys/bus/i2c/drivers/adv748x/bind
adv748x 4-0070: chip found @ 0xe0 revision 2143
adv748x 4-0070: Failed to probe TXA
adv748x: probe of 4-0070 failed with error -22
Looking at the commit which adds sub-notifiers to V4L2 it looks like
this is the intended behavior of the original commit. With this fix the
adv748x can be re-bound and still function properly.

Current implementation of __v4l2_async_notifier_parse_fwnode_endpoints()
checks first whether subdev_count >= subdev_max and only then whether
the port being parsed matches the given port index. This triggers an
error in otherwise valid cases of skipping ports that do not match.
Fix this by moving the check below the port index check.

Since commit d57ea877af ("media: rc: per-protocol repeat period"), most
IR protocols have a lower keyup timeout. This causes problems on the
ite-cir, which has default IR timeout of 200ms.
Since the IR decoders read the trailing space, with a IR timeout of 200ms,
the last keydown will have at least a delay of 200ms. This is more than
the protocol timeout of e.g. rc-6 (which is 164ms). As a result the last
IR will be interpreted as a new keydown event, and we get two keypresses.
Revert the protocol timeout to 250ms, except for cec which needs a timeout
of 550ms.
