[PATCH 3/9] phy: fix return value check in armada375_usb_phy_probe()

[Kishon Vijay Abraham I]

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

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().
