Before anything, I must say that I really liked this patch. It's
minimaly invasive to udc core and does all the necessary changes. If it
wasn't for the extra charger class, this would've been perfect.
Can't you just tie a charger to a UDC and avoid the charger class
completely?

I guess you could do this check inside
usb_gadget_set_cur_limit_by_type() itself.
