-Subject: [PATCH 3/3] ide: Clear DRQ after handling all expected accesses
-
-This is additional hardening against an end_transfer_func that fails to
-clear the DRQ status bit. The bit must be unset as soon as the PIO
-transfer has completed, so it's better to do this in a central place
-instead of duplicating the code in all commands (and forgetting it in
-some).
