Subject[PATCH 0/6] USB: iowarrior: disconnect fixes and locking cleanups
Date
This series fixes a use-after-free bug introduced by a recent
disconnect-deadlock fix that was reported by syzbot. Turns out there was
already a related bug in the driver, and the first patch addresses both
issues.

While looking at the code I found two more use-after-free bugs, which
the next two patches fix.

The next two clean up the driver by dropping two redundant locks.

Tested using a mockup device.
