Subject: tty: serial/crisv10.c: remove unnecessary null pointer check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f938f3781fa877146236042341ddbcf06bc49f0a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

tty: serial/crisv10.c: remove unnecessary null pointer check

The pointer tty is dereferened in line 3135, so it is not necessary to check
null again in line 3140.
