Subject: [PATCH] backlight: Change the return type of
 backlight_update_status() to int

Backlight device returns the result of update_status(), but
backlight_update_status() ignores it. So the consumers cannot confirm the
result of their function call. This patch makes the result to be returned
back for consumers.
