Subject: [PATCH 3/3] usb: dwc2: USB_DWC2 should depend on HAS_DMA
Date: Mon, 15 Feb 2016 12:21:45 +0100	[thread overview]
Message-ID: <1455535305-9508-4-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1455535305-9508-1-git-send-email-geert@linux-m68k.org>

If NO_DMA=y:

    ERROR: "usb_gadget_map_request" [drivers/usb/dwc2/dwc2.ko] undefined!
    ERROR: "usb_gadget_unmap_request" [drivers/usb/dwc2/dwc2.ko] undefined!
    ERROR: "bad_dma_ops" [drivers/usb/dwc2/dwc2.ko] undefined!

Add a dependency on HAS_DMA to fix this.
