From b0efc3ed0530b08e9e1cba5f63e9c251ca3d7428 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 31 Mar 2013 07:16:37 -0300 Subject: [PATCH] [media] m920x: Fix uninitialized variable warning drivers/media/usb/dvb-usb/m920x.c:91:6: warning: "ret" may be used uninitialized in this function [-Wuninitialized] drivers/media/usb/dvb-usb/m920x.c:70:6: note: "ret" was declared here This is real, if a remote control has an empty initialization sequence we would get success or failure randomly. OTOH the initialization of ret in m920x_init is needless, the function returns with an error as soon as an error happens, so the last return can only be a success and we can hard-code 0 there.
