From 0f0e2159c0c101426b705d70f43b9f423d51c869 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sat, 23 Nov 2013 13:01:50 +0100 Subject: genetlink: Fix uninitialized variable in genl_validate_assign_mc_groups() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit net/netlink/genetlink.c: In function ‘genl_validate_assign_mc_groups’: net/netlink/genetlink.c:217: warning: ‘err’ may be used uninitialized in this function Commit 2a94fe48f32ccf7321450a2cc07f2b724a444e5b ("genetlink: make multicast groups const, prevent abuse") split genl_register_mc_group() in multiple functions, but dropped the initialization of err. Initialize err to zero to fix this. Signed-off-by: Geert Uytterhoeven Signed-off-by: David S.
