Subject: sctp: reduce indent level in sctp_copy_local_addr_list
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=165f2cf6405a9e2153b69302845c7d5c9f3cb23b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sctp: reduce indent level in sctp_copy_local_addr_list

This patch is to reduce indent level by using continue when the addr
is not allowed, and also drop end_copy by using break.
