From e55a09732be9b4e13cf3b5d2b9bb41b3e60e5ea6 Mon Sep 17 00:00:00 2001 From: Frieder Schrempf Date: Fri, 2 Aug 2019 10:04:10 +0000 Subject: [PATCH] serial: sh-sci: Don't check for mctrl_gpio_init() returning -ENOSYS Now that the mctrl_gpio code returns NULL instead of ERR_PTR(-ENOSYS) if CONFIG_GPIOLIB is disabled, we can safely remove this check.
