I also commented in the RFC for two more issues.

- some udc drivers use 0-based mult, but the new
  usb_endpoint_maxp_mult() makes it 1-based.

- some udc drivers keeps bit 11 & 12 when calling the old
  usb_endpoint_maxp(), but the new version masked bit 11 & 12 already.

And here is my comment in RFC/PATCH 01/45.

"
It seems the instances which use 1 based value is less than those use 0
based. To me it seems make sense to just return 0 based value here.

Some controllers like musb writes the 0 based value to a register.
"

-Bin.
