From 59e04bc20de4bd1bd5bfa810bf04a4e50a27b9c1 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Mon, 10 Apr 2017 22:29:22 +0200 Subject: [PATCH] gpu: host1x: Fix error handling If 'devm_reset_control_get' returns an error, then we erroneously return success because error code is taken from 'host->clk' instead of 'host->rst'.
