From 77a4d757195fcf40f5cc0eaa1b6f5eb9a4d23851 Mon Sep 17 00:00:00 2001 From: Philipp Rosenberger Date: Wed, 12 Jul 2017 10:36:40 +0200 Subject: [PATCH] gpio: gpio-mxc: gpio_set_wake_irq() use proper return values Errors from enable_irq_wake() in gpio_set_wake_irq() were silently ignored. Thus led to the problem that gpio_set_wake_irq() always returned successfully, even if enable_irq_wake() returned an error.
