Use after free in drivers/media/video/em28xx/em28xx-video.c
From: Eric Sesterhenn <snakebyte@gmx.de> In several places we use dev->devno right after we kfree() dev. This fixes coverity bug id #1065 Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
