Git just sets you up for failure with its revert.  That code was from
when git was really new and now everyone gets annoyed when they see a
raw git hash without a human readable subject.  Just say at the start of
the commit message:

This reverts commit a772f116702e ("staging: vchiq: switch to
wait_for_completion_killable").

The killable version of wait_for_completion() 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. VCHIQ doesn't
fit this criteria, as it's mainly used as an interface to V4L2 and ALSA
devices.

Fixes: a772f116702e ("staging: vchiq: switch to wait_for_completion_killable")
