Subject: tcp: remove TCP_OFF and TCP_PAGE macros
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a5912db7b4f9c3ff3bd0dbb67f36484a3b21a35;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

tcp: remove TCP_OFF and TCP_PAGE macros

As mentioned by Joe Perches, TCP_OFF() and TCP_PAGE() macros are
useless.
