Subject[PATCH 4.14 237/496] ARM: davinci: fix the GPIO lookup for omapl138-hawk
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

[ 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.
