From fb3311853c0f23391fc3441d49a46d076de57757 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 15 Jan 2016 14:44:31 +0100 Subject: net: sctp: Move sequence start handling into sctp_transport_get_idx() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
