Since USB_XHCI_PLATFORM is defined in 'usb/host/Kconfig' and that's only even included if USB is defined. So it can be just: depends on (USB_XHCI_PLATFORM || USB_GADGET) && HAS_DMA That's not terribly important, though, so: Reviewed-by: Douglas Anderson <dianders@chromium.org>

Some USB controller drivers that depend on the xhci-plat driver specify this dependency using 'select' in Kconfig. This is not recommended for symbols that have other dependencies as it may lead to invalid configurations. Use 'depends on' to specify the dependency instead of 'select'. For dwc3 specify the dependency on USB_XHCI_PLATFORM in USB_DWC3_HOST and USB_DWC3_DUAL_ROLE. Also adjust the dependencies of USB_DWC3_CORE to make sure that at least one of USB_DWC3_HOST, USB_DWC3_GADGET or USB_DWC3_DUAL_ROLE can be selected.
