I tried to apply this patch on the Felipe's usb.git / testing/next branch,
but I couldn't apply because the udc-core.c was renamed to core.c.
https://git.kernel.org/cgit/linux/kernel/git/balbi/usb.git/commit/?h=testing/next&id=a22b539c7082b6a3046b3a9cebb356a047a2d81d

I guess this patch needs rebase for that.

Best regards,
Yoshihiro Shimoda
