Subject: ipv4: remove redundant verification code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d4fc6dbb5ae51430e35b2005f6d68938861f8d8b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ipv4: remove redundant verification code

The check if error signaling is wanted (inet->recverr != 0) is done by
the caller: raw.c:raw_err() and udp.c:__udp4_lib_err(), so there is no
need to check this condition again.
