From a8c2038f615ac522aa9eb55dff1b7979bef0f794 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 16 Jul 2017 19:56:38 -0300 Subject: [PATCH] PCI: qcom: Use gpiod_set_value_cansleep() to allow reset via expanders The reset GPIO can be connected to a I2C or SPI IO expander, which may sleep, so it is safer to use the gpiod_set_value_cansleep() variant instead.
