From 8b3d9cd48d15f34328ec69ecff5ca860e7068e36 Mon Sep 17 00:00:00 2001 From: Sean Wang Date: Wed, 10 Jan 2018 00:28:25 +0800 Subject: [PATCH] pinctrl: mediatek: mt7622: align error handling of mtk_hw_get_value call Make consistent error handling of all mtk_hw_get_value occurrences using propagating error code from the internal instead of creating a new one.
