[PATCH 4.14 237/496] ARM: davinci: fix the GPIO lookup for omapl138-hawk

From: Greg Kroah-Hartman
Date: Mon May 28 2018 - 06:52:04 EST


4.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

[ Upstream commit c4dc56be7e26040bfc60ce73425353516a356955 ]

The GPIO chip is called davinci_gpio.0 in legacy mode. Fix it, so that
mmc can correctly lookup the wp and cp gpios.

Note that it is the gpio-davinci driver that sets the gpiochip label to
davinci_gpio.0.
