S3C2410: add error print if we cannot add attribute
Fix the following warning by checking the result of device_create_file and printing an error but not removing the device (loss of debug registers is not fatal). drivers/video/s3c2410fb.c:905: warning: ignoring return value of 'device_create_file', declared with attribute warn_unused_result Signed-off-by: Ben Dooks <ben-linux@fluff.org> Cc: Arnaud Patard <arnaud.patard@rtp-net.org> Acked-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
