Thank you for the patch!
However, such a patch is already merged in the Felipe's usb.git repository unfortunately...
https://git.kernel.org/cgit/linux/kernel/git/balbi/usb.git/commit/?h=testing/next&id=31faf878bd8c7e2c078a3b75f65efe64f23b0f18
So, the patch will appear in linux-next repository in the future.

Best regards,
