Maciej Sosnowski 34dcc7657b dca: redesign locks to fix deadlocks ... commit eb4400e3a0 upstream. Change spin_locks to irqsave to prevent dead-locks. Protect adding and deleting to/from dca_providers list. Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls as they might sleep (use GFP_KERNEL allocation).
