Hi,
I have joined this patches into single patchset for easier
maintenance of order.
Changelog:
v2
- move endianess fix into separate patch
- use htole32() instead of mixing it with cpu_to_le32() to keep code clearer
- use correct licensing statement for Public Domain License
v1: http://www.
We wrap numeric values of fs_count and hs_count fields in htole32,
because they should be in little-endian format.

The snd-usb-audio driver has a race between close and disconnect. A
patch I have been testing reliably triggers this race on my machine and

This happens when a device is disconnected while being used for audio

Command completion events normally include command completion status,
SLOT_ID, and a pointer to the original command. Reset device command
completion SLOT_ID may be zero according to xhci specs 4.6.11.
VIA controllers set the SLOT_ID to zero, triggering a WARN_ON in the
