usb: typec: hd3ss3220: hd3ss3220_probe() warn: passing zero to 'PTR_ERR'
This patch fixes the warning passing zero to 'PTR_ERR' by changing the
check from 'IS_ERR_OR_NULL' to 'IS_ERR'. Also improved the error handling
on probe function.
Fixes: 1c48c759ef4b ("usb: typec: driver for TI HD3SS3220 USB Type-C DRP port controller")
