d20796627f scsi: hptiop: Replace one-element array with flexible-array member in struct hpt_iop_request_ioctl_command()
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct hpt_iop_request_ioctl_command.

c682df7199 scsi: hptiop: Replace one-element array with flexible-array member
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct hpt_iop_request_scsi_command and refactor the rest of the
code, accordingly.

The following pieces of code suggest that the one element of array sg_list
in struct hpt_iop_request_scsi_command is not taken into account when
calculating the total size for both struct hpt_iop_request_scsi_command and
the maximum number of elements sg_list will contain:

1047         req->header.size = cpu_to_le32(
1048                                 sizeof(struct hpt_iop_request_scsi_command)
1049                                  - sizeof(struct hpt_iopsg)
1050                                  + sg_count * sizeof(struct hpt_iopsg));

1400         req_size = sizeof(struct hpt_iop_request_scsi_command)                            1401                 + sizeof(struct hpt_iopsg) * (hba->max_sg_descriptors - 1);

So it's safe to replace the one-element array with a flexible-array member
and update the code above, accordingly: now we don't need to subtract
sizeof(struct hpt_iopsg) from sizeof(struct hpt_iop_request_scsi_command)
because this is implicitly done by the flex-array transformation.

5c113eb3bc scsi: hptiop: Stop using the SCSI pointer
Set .cmd_size in the SCSI host template instead of using the SCSI pointer
from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer
from struct scsi_cmnd.

Rename hpt_scsi_pointer into hpt_cmd_priv because that data structure is
not related to struct scsi_pointer.

ede1e6f8b4 [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver
HighPoint RocketRAID 3220/3320 series 8 channel PCI-X SATA RAID Host
Adapters.

Fixes from original submission:

Merge Andrew Morton's patches:
- Provide locking for global list
- Fix debug printks
- uninline function with multiple callsites
- coding style fixups
- remove unneeded casts of void*
- kfree(NULL) is legal

- replace mdelay with msleep
- add pci posting flush
- do not set pci command reqister in map_pci_bar
- do not try merging sg elements in hptiop_buildsgl()
