Subject: net_sched: remove redundant assignment to ret
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b1c49d14200dae47544f7ea6ee9040ded01f8425;p=linux.git

net_sched: remove redundant assignment to ret

The assignment of -EINVAL to variable ret is redundant as it
is being overwritten on the following error exit paths or
to the return value from the following call to basic_set_parms.
Fix this up by removing it. Cleans up clang warning message:

net/sched/cls_basic.c:185:2: warning: Value stored to 'err' is never read

Fixes: 1d8134fea2eb ("net_sched: use idr to allocate basic filter handles")
