We already know status is negative because of the earlier check so there
is no need to check again.

Autogain algorithm is very simple, if average luminance is low - increase gain,
if it's high - decrease gain. Gain granularity is low enough for this algo to
stabilize quickly.

This cam seems to return different values on long commands, so make status check
in sn9c2028_long_command() more tolerant. Anyway, read value isn't used anywhere
later.

Instead use v4l2_dbg and v4l2_err. Note that the PDEBUG macro is kept to
make this patch-set less invasive, but it is simply a wrapper around
v4l2_dbg now. Most of the other changes are there to make the dev parameter
for the v4l2_xxx macros available everywhere we do logging.
