Oded Gabbay a015c1e926 iommu/amd: fix accounting of device_state ... This patch fixes a bug in the accounting of the device_state. In the current code, the device_state was put (decremented) too many times, which sometimes lead to the driver getting stuck permanently in put_device_state_wait(). That happen because the device_state->count would go below zero, which is never supposed to happen. The root cause is that the device_state was decremented in put_pasid_state() and put_pasid_state_wait() but also in all the functions that call those functions. Therefore, the device_state was decremented twice in each of these code paths. The fix is to decouple the device_state accounting from the pasid_state accounting - remove the call to put_device_state() from the put_pasid_state() and the put_pasid_state_wait()) Signed-off-by: Oded Gabbay <oded.gabbay@amd.com>		2014-11-10 10:57:36 +02:00
