Subject: sctp: Remove some redundant code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e8bc8f9a670e26e91562e724a2114243898bd616;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

sctp: Remove some redundant code

In commit 311b21774f13 ("sctp: simplify sk_receive_queue locking"), a call
to 'skb_queue_splice_tail_init()' has been made explicit. Previously it was
hidden in 'sctp_skb_list_tail()'

Now, the code around it looks redundant. The '_init()' part of
'skb_queue_splice_tail_init()' should already do the same.
