    Subject[PATCH 5.9 243/391] usb: dwc3: core: add phy cleanup for probe error handling
    Date
    From: Li Jun <jun.li@nxp.com>

    commit 03c1fd622f72c7624c81b64fdba4a567ae5ee9cb upstream.

    Add the phy cleanup if dwc3 mode init fail, which is the missing part of
    de-init for dwc3 core init.

    Fixes: c499ff71ff2a ("usb: dwc3: core: re-factor init and exit paths")
