Subject[PATCH 03/12] backlight: gpio: pull the non-pdata device probing code into probe()
Date
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

There's no good reason to have the generic probing code in a separate
routine. This function is short and is inlined by the compiler anyway.
Move it into probe under the pdata-specific part.
