From ea04a7cae32108624af55d84845e8f4d21c9cb34 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 24 Feb 2016 21:31:14 +0800 Subject: [PATCH] gpio: pisosr: Use gpiod_set_value_cansleep in pisosr_gpio_refresh() This driver has .can_sleep flag set. So the pisosr_gpio_get() can be called from contexts that can sleep. Thus use the cansleep() variant in pisosr_gpio_refresh().
