One of the problems of the old CHECK_ERROR is that it was hiding
the status parameter. Maybe due to that, on a few places, the return
code might lead to return incorrect status:

The CHK_ERROR macro does a flow control, violating chapter 12
of the Documentation/CodingStyle. Doing flow controls inside
macros is a bad idea, as it hides what's happening. It also
hides the var "status" with is also a bad idea.

The changes were done by this small perl script:
	my $blk=0;
	while (<>) {
		s/^\s+// if ($blk);
		$f =~ s/\s+$// if ($blk && /^\(/);
		$blk = 1 if (!m/\#/ && m/CHK_ERROR/);
		$blk=0 if ($blk && m/\;/);
		s/\n/ / if ($blk);
		$f.=$_;
	};
	$f=~ s,\n(\t+)CHK_ERROR\((.*)\)\;([^\n]*),\n\1status = \2;\3\n\1if (status < 0)\n\1\tbreak;,g;

	print $f;

And manually fixed.

By default no control events are sent to the application that caused the
control value or flags change (i.e. the control(s) passed to VIDIOC_S_CTRL
or VIDIOC_S_EXT_CTRLS). But if a change in one control causes a change in
another control that was not part of the control(s) in VIDIOC_S_CTRL or
S_EXT_CTRLS, then the application should be notified.
