Subject: [PATCH] usb: musb: mediatek: don't unregister something that wasn't registered
Git-commit: ba883de971d1ad018f3083d9195b8abe54d87407
Patch-mainline: v6.3-rc1
References: git-fixes
This function only calls mtk_otg_switch_init() when the ->port_mode
is MUSB_OTG so the clean up code should only call mtk_otg_switch_exit()
for that mode.
Fixes: 0990366bab3c ("usb: musb: Add support for MediaTek musb controller")
