Hi Greg

V2 of xhci features and cleanups for usb-next, including xhci dbc
cleanups, MSI rework, and fixing how we reconfigure max packet size
for xhc.

One patch fixes a null pointer deref issue, but this hasn't been seen
in real life. It's a theoretical case triggered by adding a 3 second
delay in the driver.
So I don't think it should go to stable.

v2 drops one small cleanup patch as it turned out to not really clarify or
simplify things. This was [PATCH 08/19] "xhci: dbc: Use sizeof_field()
 where it makes sense" in previous series.

Thanks
