Subject: [2.6 patch] dvb_frontend_ioctl(): fix check-after-use
Date: Tue, 31 Jul 2007 00:28:17 +0200 [thread overview]
Message-ID: <20070730222817.GE3972@stusta.de> (raw)
The Coverity checker spotted that we have already oops'ed if "fe" was NULL.
Since "fe" being NULL seems impossible at this point this patch removes
the NULL check.
