Subject: usb: renesas_usbhs: gadget: fix return value check in usbhs_mod_gadget_probe()

From: Wei Yongjun <weiyj.lk@gmail.com>

commit 3295235fd70ed6d594aadee8c892a14f6a4b2d2e upstream.

In case of error, the function usb_get_phy() returns ERR_PTR() and never
returns NULL. The NULL test in the return value check should be replaced
with IS_ERR().

	provide VBUS")
