You should probably update the subject line because now it's not just
about parentheses any more.
[PATCH v2] Staging: rtlwifi: clean up crc16_ccitt()
So the one thing per patch rule is a little bit about selling your
patch. We never allow "Clean up whole_file.c" but we do sometimes allow
"Clean up a function()" so long as the patch description sells it in
the right way.
Blah blah function does "BIT(0) << i" instead of "BIT(i)". Using !!
is slightly shorter than "foo ? 1 : 0". Blah blah, etc.

I thought your Coccinelle script was going to complain about these
parentheses. Probably the &= confuses it? There are a couple others
in the same function.
