From 740f5b08d48956fa9644f2048081f129058e205a Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Thu, 11 Feb 2016 15:34:08 +0100 Subject: [PATCH] pinctrl: mediatek: fix handling return value of mtk_pmx_find_gpio_mode The function can return negative values, so its result should be assigned to signed variable. The problem has been detected using coccinelle semantic patch scripts/coccinelle/tests/assign_signed_to_unsigned.cocci.
