From 87993273feb7f9379ec79cd9c25d195c4b93b7da Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Tue, 23 Sep 2014 21:05:37 +0200 Subject: pinctrl: samsung: Make samsung_pinctrl_get_soc_data use ERR_PTR() Currently the function returns a valid pointer on success and NULL on error, so exact error code is lost. This patch changes return convention of the function to use ERR_PTR() on error instead.
