Dave Jiang 40e3b5c128 dmaengine: idxd: check device state before issue command ... [ Upstream commit 89e3becd8f821e507052e012d2559dcda59f538e ] Add device state check before executing command. Without the check the command can be issued while device is in halt state and causes the driver to block while waiting for the completion of the command.
