From b03c29c1b13afa18ee88cce07bbe87298eb0d3a3 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 15 Jan 2020 14:30:34 +0000 Subject: ASoC: rt711: fix return value check in rt711_sdw_probe() In case of error, the function devm_regmap_init() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
