From 71fd5d07b791b90587f695f048ad82e8d4c1c67e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 8 Jun 2018 12:05:47 +0200 Subject: [PATCH] pinctrl: actions: Fix uninitialized error in owl_pin_config_set() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit With gcc 4.1.2: drivers/pinctrl/actions/pinctrl-owl.c: In function ‘owl_pin_config_set’: drivers/pinctrl/actions/pinctrl-owl.c:336: warning: ‘ret’ may be used uninitialized in this function Indeed, if num_configs is zero, the uninitialized value will be returned as an error code. Fix this by preinitializing it to zero.
