remoteproc: qcom: wcss: Fix return value check in q6v5_wcss_init_mmio()
In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Fixes: 0af65b9b915e ("remoteproc: qcom: wcss: Add non pas wcss Q6 support for QCS404") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Link: https://lore.kernel.org/r/20210319094100.4185044-1-weiyongjun1@huawei.com Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
