    Subject[PATCH 4.11 019/114] usb: Make sure usb/phy/of gets built-in
    Date
    4.11-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Alexey Brodkin <Alexey.Brodkin@synopsys.com>

    commit 3d6159640da9c9175d1ca42f151fc1a14caded59 upstream.

    DWC3 driver uses of_usb_get_phy_mode() which is
    implemented in drivers/usb/phy/of.c and in bare minimal
    configuration it might not be pulled in kernel binary.

    In case of ARC or ARM this could be easily reproduced with
    "allnodefconfig" +CONFIG_USB=m +CONFIG_USB_DWC3=m.

    On building all ends-up with:
    ---------------------->8------------------
    Kernel: arch/arm/boot/Image is ready
    Kernel: arch/arm/boot/zImage is ready
    Building modules, stage 2.
    MODPOST 5 modules
    ERROR: "of_usb_get_phy_mode" [drivers/usb/dwc3/dwc3.ko] undefined!
    make[1]: *** [__modpost] Error 1
    make: *** [modules] Error 2
    ---------------------->8------------------
