From bec145ae6f6978f0319e5600a742f45f76ecc4dd Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 18 Nov 2009 10:31:57 +0200 Subject: [PATCH] ALSA: remove unnecessary null check This function is only called from snd_ctl_ioctl() and the file parameter can never be null so there is no need to check it here. We dereference file at the start of the function: struct snd_card *card = file->card; and it confuses static checkers to dereference a pointer before checking it.
