From ee27aa901805dfc9c3a5eb5f0948eba9ab481ba1 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 24 Jul 2014 16:50:03 -0300 Subject: [media] coda: fix build error by making reset control optional make reset control optional for i.MX27 The patch "[media] coda: add reset control support" introduced a build failure if CONFIG_RESET_CONTROLLER is disabled: drivers/media/platform/coda.c:3734:2: error: implicit declaration of function 'devm_reset_control_get' Since not all SoCs containing CODA VPUs do have a system reset controller, use devm_reset_control_get_optional to make it optional.
