[PATCH v2] usb: renesas_usbhs: gadget: fix return value check in usbhs_mod_gadget_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei Yongjun <weiyj.lk@xxxxxxxxx>

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().

Fixes: b5a2875605ca ("usb: renesas_usbhs: Allow an OTG PHY driver to
	provide VBUS")
