Subject: [PATCH net-next] net: ipv4: Fix some kerneldoc warnings in TCP Low Priority

net//ipv4/tcp_lp.c:120: warning: Function parameter or member 'sk' not described in 'tcp_lp_cong_avoid'
net//ipv4/tcp_lp.c:135: warning: Function parameter or member 'sk' not described in 'tcp_lp_remote_hz_estimator'
net//ipv4/tcp_lp.c:188: warning: Function parameter or member 'sk' not described in 'tcp_lp_owd_calculator'
net//ipv4/tcp_lp.c:222: warning: Function parameter or member 'rtt' not described in 'tcp_lp_rtt_sample'
net//ipv4/tcp_lp.c:222: warning: Function parameter or member 'sk' not described in 'tcp_lp_rtt_sample'
net//ipv4/tcp_lp.c:265: warning: Function parameter or member 'sk' not described in 'tcp_lp_pkts_acked'
net//ipv4/tcp_lp.c:97: warning: Function parameter or member 'sk' not described in 'tcp_lp_init'

There are still a few kerneldoc warnings after this fix.
