These patches are based on Linus's tree
The changes are:
- improve handling for sync requests
ensure controller is ready for requests
- improve-error-checking-for-sync-requests
detect rare error cases for synchronous requests
- add more supported devices
- fix critical ARM issue
From: Kevin Barnett
- decrement the active thread count after
the synchronous request was submitted to the controller but before
the driver blocks to wait for the request to complete.
