[PATCH 0/5] snd-usb endpoint rework, take 5

[Daniel Mack <zonque@gmail.com>]

I actually wanted to wait for more input, but as the flaws reported so
far were rather minor, I addressed to following details in this new
round as mentioned by Takashi and Clemens:

 - removed the faulty "(!u || u->urb)" check
 - guard the result of min() with the spinlock inside next_packet_size()
 - removed the tasklet and made the handler a function that is called
   in-place

Thanks again for the reviews, and keep them coming :)
