Subject: [PATCH] Staging: comedi: fix redundant parens in return in amplc_dio200_common.c

This patch fixes a coding style issue found by the checkpatch.pl tool in
amplc_dio200_common.c by removing the unnecessary parentheses around the
expression in a return statement.

When I run checkpatch.pl it doesn't find any errors and the parenthesis
haven't been removed. How are you running checkpatch.pl? Are you using
any extra options?

It looks like that I accidentally ran the file trough an older version
of checkpatch.pl. The error for this case was quieted in commit
5b9553a (checkpatch: make "return is not a function" test quieter).

Sorry for the noise.

If you are looking for something easy to fix have a look in

drivers/staging/rtl8192u/

There are lots of checkpatch errors to fix in there.
