Subject: [TCP]: Fix unlikely usage in tcp_transmit_skb()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83de47cd0c5738105f40e65191b0761dfa7431ac;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[TCP]: Fix unlikely usage in tcp_transmit_skb()

The following unlikely should be replaced by likely because the
condition happens every time unless there is a hard error to transmit
a packet.
