Make these const as they are only stored in the type field of a device structure, which is const. Done using Coccinelle. Signed-off-by:

There's no need to keep the private data for a device in a separate list; better to store it in ->hostdata and do away with the additional list. Signed-off-by:

megaraid_mbox only has one reset function, and that is a host reset. So drop the duplicate bus reset and device reset functions. Signed-off-by:

bus reset always returns SUCCESS, meaning host reset was never tested. At the same time the only difference to the HBA is a missing call to NCR_700_chip_reset(). So add the missing call to bus reset, drop host reset, and move bus reset to host reset. Signed-off-by:

The driver has both a bus and a host reset, where the host reset does a bus reset followed by an attempt to reset the chip registers to a default state. However, as the bus reset always returned SUCCESS the host reset was never called, so the functionality of the register reset function was never validated. Additionally, tha AIC-6260 chip has a hard reset line, which actually should be preferred for a host reset. But I haven't found a way how this can be triggered via software, so take the safe approach and drop the host reset. [mkp: typo] Signed-off-by:

bus reset is a host reset without nsp32hw_init(), and will always return SUCCESS, thus disabling the use of host reset. So drop bus reset in favour of host reset. Signed-off-by:

qedf has a host reset handler, but as the bus reset handler is a stub always returning SUCCESS the host reset is never invoked. So drop the bus reset handler. Signed-off-by:

The bus reset function is just a wrapper calling host reset under the host lock. So move taking of the host lock into the host reset function and drop bus reset. Signed-off-by:

The Highpoint driver only has one reset function, and that is a host reset. So stop pretending we're doing anything else. Signed-off-by:

The bus reset handler is just calling target reset on all targets, which is exactly what SCSI EH will be doing anyway. So move the bus reset function to target reset and drop the loop. Signed-off-by:

The bus reset handler is calling I_T Nexus reset, which logically is a target reset as it need to specify both the initiator and the target. So move it to target reset. Signed-off-by:

Command abort already returns FAILED, which will then be escalated to a host reset. So no need to call host_reset directly. Signed-off-by:

When calling host reset we're resetting all ports anyway, so there is no point in waiting for the ports to become unblocked. Signed-off-by:

When we're resetting the host any remote port states will be reset anyway, so it's pointless to wait for dev_loss_tmo during host reset. Signed-off-by:

Before scsi_prep_fn() calls the ULP .init_command() callback function it stores the SCSI command pointer in request.special. This means that the SCpnt = rq->special assignments in the sd and sr drivers assign a pointer to itself. Hence convert these two assignment statements into warning statements. Signed-off-by:

Since commit e9c787e6 ("scsi: allocate scsi_cmnd structures as part of struct request") struct request and struct scsi_cmnd are adjacent. This means that there is now an alternative to reading req->special to convert a pointer to a prepared request into a SCSI command pointer, namely by using blk_mq_rq_to_pdu(). Make this change where appropriate. Although this patch does not change any functionality, it slightly improves performance and slightly improves readability. Signed-off-by:
