cd2268a180 scsi: pm8001: Fix command initialization in pm8001_chip_ssp_tm_req() 
The ds_ads_m field of struct ssp_ini_tm_start_req has the type __le32.
Assigning a value to it should thus use cpu_to_le32(). This fixes the
sparse warning:

warning: incorrect type in assignment (different base types)
   expected restricted __le32 [addressable] [assigned] [usertype] ds_ads_m
   got int

3762d8f6ed scsi: pm8001: Fix pm80xx_pci_mem_copy() interface 
The declaration of the local variable destination1 in pm80xx_pci_mem_copy()
as a pointer to a u32 results in the sparse warning:

warning: incorrect type in assignment (different base types)
    expected unsigned int [usertype]
    got restricted __le32 [usertype]

Furthermore, the destination" argument of pm80xx_pci_mem_copy() is wrongly
declared with the const attribute.

Fix both problems by changing the type of the "destination" argument to
"__le32 *" and use this argument directly inside the pm80xx_pci_mem_copy()
function, thus removing the need for the destination1 local variable.

1a37b6738b scsi: pm8001: Fix command initialization in pm80XX_send_read_log() 
Since the sata_cmd struct is zeroed out before its fields are initialized,
there is no need for using "|=" to initialize the ncqtag_atap_dir_m
field. Using a standard assignment removes the sparse warning:

warning: invalid assignment: |=

Also, since the ncqtag_atap_dir_m field has type __le32, use cpu_to_le32()
to generate the assigned value.

8454563e4c scsi: libsas: Fix sas_ata_qc_issue() handling of NCQ NON DATA commands 
To detect for the DMA_NONE (no data transfer) DMA direction,
sas_ata_qc_issue() tests if the command protocol is ATA_PROT_NODATA.  This
test does not include the ATA_CMD_NCQ_NON_DATA command as this command
protocol is defined as ATA_PROT_NCQ_NODATA (equal to ATA_PROT_FLAG_NCQ) and
not as ATA_PROT_NODATA.

To include both NCQ and non-NCQ commands when testing for the DMA_NONE DMA
direction, use "!ata_is_data()".

db22de3eb0 scsi: iscsi: Stop using the SCSI pointer 
Instead of storing the iSCSI task pointer and the session age in the SCSI
pointer, use command-private variables. This patch prepares for removal of
the SCSI pointer from struct scsi_cmnd.

The list of iSCSI drivers has been obtained as follows:
$ git grep -lw iscsi_host_alloc
drivers/infiniband/ulp/iser/iscsi_iser.c
drivers/scsi/be2iscsi/be_main.c
drivers/scsi/bnx2i/bnx2i_iscsi.c
drivers/scsi/cxgbi/libcxgbi.c
drivers/scsi/iscsi_tcp.c
drivers/scsi/libiscsi.c
drivers/scsi/qedi/qedi_main.c
drivers/scsi/qla4xxx/ql4_os.c
include/scsi/libiscsi.h

Note: it is not clear to me how the qla4xxx driver can work without this
patch since it uses the scsi_cmnd::SCp.ptr member for two different
purposes:
- The qla4xxx driver uses this member to store a struct srb pointer.
- libiscsi uses this member to store a struct iscsi_task pointer.
