Subject: tcp: md5: fix a typo in tcp_v4_md5_lookup()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b52e69217b5a02469f8431934f59c0d7103dd32f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tcp: md5: fix a typo in tcp_v4_md5_lookup()

Lookup key for tcp_md5_do_lookup() has to be taken
from addr_sk, not sk (which can be the listener)

Fixes: fd3a154a00fb ("tcp: md5: get rid of tcp_v[46]_reqsk_md5_lookup()")
