| Subject: scsi: mpi3mr: Fix reporting of actual data transfer size |
| |
| From: Sreekanth Reddy <sreekanth.reddy@broadcom.com> |
| |
| [ Upstream commit 9992246127246a27cc7184f05cce6f62ac48f84e ] |
| |
| The driver is missing to set the residual size while completing an |
| I/O. Ensure proper data transfer size is reported to the kernel on I/O |
| completion based on the transfer length reported by the firmware. |
