This patch adds the following warnings to the build:
	drivers/staging/udlfb/udlfb.c:1439: warning: ignoring return value of ‘device_create_file’, declared with attribute warn_unused_result
	drivers/staging/udlfb/udlfb.c:1441: warning: ignoring return value of ‘device_create_bin_file’, declared with attribute warn_unused_result

care to fix it up with a follow-on patch?

thanks,
