From 2e6424ab852a24cac6d918f3ee002e57febe02c3 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Wed, 9 Aug 2017 11:09:33 -0500 Subject: [PATCH] pinctrl: amd: fix error return code in amd_gpio_probe() platform_get_irq() returns an error code, but the pinctrl-amd driver ignores it and always returns -EINVAL. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Print and propagate the return value of platform_get_irq on failure. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
