From 2077ee796fefb8f80d43b5318e6f1b54d235a3ea Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 18 Jul 2006 15:28:09 -0300 Subject: Check __must_check warning in video_device_create_file From: Michael Krufky This patch moves the check from bttv-driver.c into v4l2-dev.h, because all other callers of video_device_create_file must also be checked.
