Subject: ALSA: remove unnecessary null check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bec145ae6f6978f0319e5600a742f45f76ecc4dd;p=linux-beck.git

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.
