Subject: net/sched: remove unneeded NULL check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=00093fab980d0a8950a64bdf9e346d0497b9a7e4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net/sched: remove unneeded NULL check

There is no need to check "s".  nla_data() doesn't return NULL.  Also we
already dereferenced "s" at this point so it would have oopsed ealier if
it were NULL.
