From d0593c363f04ccc4bc7b6939c24a0ee65391c779 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Mon, 20 Jun 2016 08:40:22 +0200 Subject: [PATCH] pinctrl: sh-pfc: Propagate errors on group config On group configuration, bail out if setting one of the individual pins fails. We don't need to roll-back, the pinctrl core will do this for us.
