[PATCH 6/6] slimbus: qcom: Fix return value check in qcom_slim_probe()

[srinivas . kandagatla]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

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().
