Subject[PATCH 39/47] v4l-dev2: handle __must_check
Date
From: Andrew Morton <akpm@osdl.org>

We get hundreds of these:

include/media/v4l2-dev.h:348: warning: ignoring return value of 'class_device_create_file', declared with attribute warn_unused_result

Handle it, and propagate the __must_check back a level.
