From 2efeec2d035ca4901ca5d53262c814935b730f44 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 12 Jul 2016 08:02:28 -0300 Subject: [PATCH] [media] vcodec: mediatek: Fix return value check in mtk_vcodec_init_enc_pm() In case of error, the function devm_clk_get() returns ERR_PTR() and not returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
