Subject: inet: convert tcp_early_demux and udp_early_demux to u8
X-Git-Tag: v5.15~1236^2~378^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2932bcda070d9a02548e57119b1ada8f018c40b5;p=platform%2Fkernel%2Flinux-starfive.git

inet: convert tcp_early_demux and udp_early_demux to u8

For these sysctls, their dedicated helpers have
to use proc_dou8vec_minmax().
