I have some bones to gnaw.  Not specific to this patch ;)

Lots of people are doing this "video: backlight: adp8870:" thing
lately.  And it's good, but why not just use
"drivers/video/backlight/adp8860_bl.c" to identify the affected
susbsytem/file/etc?  It's simple and uniform.  It's not always the
appropriate thing to do, but replacing the /'s with ": " seems rather
random and pointless.

Secondly, no, the point of this patch is not to fix a
warn_unused_result() warning!  The patch actually fixes a bug: the code
wasn't checking the strict_strtoul() return value.  The warning is
simply what alerted us to the bug.

So I renamed this patch to

	drivers/video/backlight/adp8860_bl.c: check strict_strtoul() return value
