    Subject[PATCH AUTOSEL 4.9 125/251] usb: gadget: fsl: fix link error against usb-gadget module
    Date
    From: Arnd Bergmann <arnd@arndb.de>

    [ Upstream commit 2100e3ca3676e894fa48b8f6f01d01733387fe81 ]

    The dependency to ensure this driver links correctly fails since
    it can not be a loadable module:

    drivers/usb/phy/phy-fsl-usb.o: In function `fsl_otg_set_peripheral':
    phy-fsl-usb.c:(.text+0x2224): undefined reference to `usb_gadget_vbus_disconnect'

    Make the option 'tristate' so it can work correctly.

    Fixes: 5a8d651a2bde ("usb: gadget: move gadget API functions to udc-core")
