Quick correction: looks like[*] 3.1 is also affected due to
58c244009ef6 ("Input: ads7846 - cleanup GPIO initialization").  Sorry
I missed that before.

drivers/input/touchscreen/ads7846.c: In function 'ads7846_setup_pendown':
drivers/input/touchscreen/ads7846.c:970: error: implicit declaration of
function 'gpio_request_one'

Hope that helps,
Jonathan
