Subject: [PATCH 5.3 10/48] tcp: remove redundant new line from tcp_event_sk_skb

From: Tony Lu <tonylu@...ux.alibaba.com>

[ Upstream commit dd3d792def0d4f33bbf319982b1878b0c8aaca34 ]

This removes '\n' from trace event class tcp_event_sk_skb to avoid
redundant new blank line and make output compact.

Fixes: af4325ecc24f ("tcp: expose sk_state in tcp_retransmit_skb tracepoint")
