[PATCH] phy: rockchip-inno-usb2: Return zero after otg sync

From: Peter Geis
Date: Mon Aug 22 2022 - 06:33:36 EST


The otg sync state patch reuses the ret variable, but fails to set it to
zero after use. This leads to a situation when the otg port is in
peripheral mode where the otg phy aborts halfway through setup. Fix this
by setting ret to zero after use.

Fixes: 8dc60f8da22f ("phy: rockchip-inno-usb2: Sync initial otg state")
