Subject: gpio: pisosr: Use devm_gpiod_get_optional for gpio->load_gpio
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ea1361fd5f26f1dbb369f85b3ad42a84c133e7e1;p=linux-beck.git

gpio: pisosr: Use devm_gpiod_get_optional for gpio->load_gpio

gpio->load_gpio is optional, so use devm_gpiod_get_optional instead.
