Subject: [PATCH] staging: comedi: pcl816: if test should use logical OR not bitwise OR
Date: Thu, 7 Jun 2012 17:25:35 -0700 [thread overview]
Message-ID: <201206071725.35720.hartleys@visionengravers.com> (raw)
This quiets a couple sparse warnings about:
warning: dubious: !x | !y
warning: dubious: x | !y
Also, remove the unnecessary parentheses abound the variables.
