The vchiq code tends to follow a coding pattern that's not accepted as
per the Linux kernel coding style

We have this:
	if (expression != 0)

We want this:
	if (expression)

We make an exception if the expression refers to a size, in which case
it's accepted for the sake of clarity.

The killable version of wait_event() is meant to be used on situations
where it should not fail at all costs, but still have the convenience of
being able to kill it if really necessary. Wait events in VCHIQ doesn't
fit this criteria, as it's mainly used as an interface to V4L2 and ALSA
devices.
