drivers/video/aty/radeon_base.c: notify user if sysfs_create_bin_file() failed
Current kernel builds warn about: drivers/video/aty/radeon_base.c: In function 'radeonfb_pci_register': drivers/video/aty/radeon_base.c:2334: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result drivers/video/aty/radeon_base.c:2336: warning: ignoring return value of 'sysfs_create_bin_file', declared with attribute warn_unused_result Do minimal checking of these functions and issue a warning if either fails. They don't seem to be critical.. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Cc: "Antonino A.
