From 6e6b1ada0c6a745b0190016b1f50b699a625a944 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 10 Oct 2018 03:59:39 +0000 Subject: [PATCH] remoteproc: qcom: qcom_q6v5_adsp: Fix some return value check In case of error, the functions devm_kcalloc() and devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Also removed -EPROBE_DEFER check since devm_kcalloc never return this error.
