From: Geert Uytterhoeven Date: Fri, 15 Jan 2016 13:44:31 +0000 (+0100) Subject: net: sctp: Move sequence start handling into sctp_transport_get_idx() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb3311853c0f23391fc3441d49a46d076de57757;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: sctp: Move sequence start handling into sctp_transport_get_idx() net/sctp/proc.c: In function ‘sctp_transport_get_idx’: net/sctp/proc.c:313: warning: ‘obj’ may be used uninitialized in this function This is currently a false positive, as all callers check for a zero offset first, and handle this case in the exact same way. Move the check and handling into sctp_transport_get_idx() to kill the compiler warning, and avoid future bugs.
