    Subject[PATCH 4.14 187/239] phy: renesas: rcar-gen3-usb2: fix vbus_ctrl for role sysfs
    Date
    From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

    [ Upstream commit 09938ea9d136243e8d1fed6d4d7a257764f28f6d ]

    This patch fixes and issue that the vbus_ctrl is disabled by
    rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot
    supply the vbus.

    Note that this condition will exit when the otg irq happens
    even if we don't apply this patch.
