remoteproc: qcom: wcnss: Fix return value check in wcnss_probe()
In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
