-Subject: [PATCH] ide: ahci: reset ncq object to unused on error
-
-When processing NCQ commands, ACHI device emulation prepares a
-NCQ transfer object; To which an aio control block(aiocb) object
-is assigned in 'execute_ncq_command'. In case, when the NCQ
-command is invalid, the 'aiocb' object is not assigned, and NCQ
-transfer object is left as 'used'. This leads to a use after
-free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
-Reset NCQ transfer object to 'unused' to avoid it.
