Subject: RE: [PATCH] usb: host: USB_XHCI_RZV2M depends on USB_GADGET

Hi Tom,

Thanks for the patch.

Arnd send a patch for refactoring the USB_XHCI_RZV2M KConfig dependencies related to USB_GADGET on [1] and
is in usb-next. Do you see this issue after applying[1]?

[1] https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/commit/?h=usb-next&id=ec5499d338ece9db9b7590649d3cfcc4d7f9603d

Cheers,
Biju
