Subject: Input: soc_button_array - use gpio_is_valid()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=be8e7a7ec876d509bc61af64b41b314a142aa262;p=linux-beck.git

Input: soc_button_array - use gpio_is_valid()

gpio_keys will later use gpio_is_valid(). To match the actual
behavior, we should use it here too.
