Subject: Re: [PATCH v2 2/2] Revert "usb: dwc3: Don't switch OTG -> peripheral if extcon is present"

This revert breaks USB on the Lenovo Yoga C630.

sudo cat /sys/kernel/debug/devices_deferred
a800000.usb     platform: supplier 88e3000.phy not ready
88e2000.phy
88e3000.phy
a600000.usb     platform: supplier 88e2000.phy not ready

Nothing seems to indicate there is any breakage in the dmesg output though, just
that deferred probe is pending.
