Looks like a good change but the topic tag ('backlight:') looks a bit
generic for something that only impacts the lm3533_bl.c driver.

Also it would be good if this patchset included the same fix
for *all* drivers that a grep shows contain this code pattern
(e.g. git grep 'return scnprintf.*PAGE_SIZE').
