Subject: sctp: remove return value from sctp_packet_init/config
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66b91d2cd0344c417194596ef6e387e52be69e57;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

sctp: remove return value from sctp_packet_init/config

There is no reason to use this cascading. It doesn't add anything.
Let's remove it and simplify.
