Subject: [patch] staging: comedi: pcmuio: remove an unneeded check
Date: Tue, 20 Aug 2013 09:00:14 +0000 [thread overview]
Message-ID: <20130820090013.GC20170@elgon.mountain> (raw)
"devpriv" is non-NULL at this point. We dereference it earlier in the
function and the inconsistent checking upsets static checkers. We don't
need to check "devpriv->sprivs" because kfree() accepts NULL pointers.
