The code has existed in this exact form at least since v2.6.12, and the
warning seems correct. This uses named initializers to ensure we
initialize all members of the structure.

f46e7cd36b scsi: advansys: fix build warning for PCI=n
The advansys probe function tries to handle both ISA and PCI cases, each
hidden in an #ifdef when unused. This leads to a warning indicating that
when PCI is disabled we could be using uninitialized data:

drivers/scsi/advansys.c: In function  advansys_board_found :
drivers/scsi/advansys.c:11036:5: error:  ret  may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/scsi/advansys.c:10928:28: note:  ret  was declared here
drivers/scsi/advansys.c:11309:8: error:  share_irq  may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/scsi/advansys.c:10928:6: note:  share_irq  was declared here

This cannot happen in practice because the hardware in question only
exists for PCI, but changing the code to just error out here is better
for consistency and avoids the warning.

757b22f9d5 advansys: fix big-endian builds
Building the advansys driver in a big-endian configuration such as
ARM allmodconfig shows a warning:

 drivers/scsi/advansys.c: In function 'adv_build_req':
 include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer implicitly truncated to unsigned type [-Woverflow]
  #define __cpu_to_le32(x) ((__force __le32)__swab32((x)))
 drivers/scsi/advansys.c:7806:22: note: in expansion of macro 'cpu_to_le32'
   scsiqp->sense_len = cpu_to_le32(SCSI_SENSE_BUFFERSIZE);

It turns out that the commit that introduced this used the cpu_to_le32()
incorrectly on an 8-bit field, which results in the sense_len to always
be set to zero, as the SCSI_SENSE_BUFFERSIZE value gets moved to upper
byte of the 32-bit intermediate.

This removes the cpu_to_le32() call to restore the original version.

I found this only by looking at the compiler output and have not done a
full review for possible further endianess bugs in the same driver.

I/O path by always enabling block tagging, and always using host wide

coverage of over tagging setup over different configs.

c8b09f6fb6 scsi: don't set tagging state from scsi_adjust_queue_depth
Remove the tagged argument from scsi_adjust_queue_depth, and just let it
handle the queue depth.  For most drivers those two are fairly separate,
given that most modern drivers don't care about the SCSI "tagged" status
of a command at all, and many old drivers allow queuing of multiple
untagged commands in the driver.

Instead we start out with the ->simple_tags flag set before calling
->slave_configure, which is how all drivers actually looking at
->simple_tags except for one worke anyway.  The one other case looks
broken, but I've kept the behavior as-is for now.

Except for that we only change ->simple_tags from the ->change_queue_type,
and when rejecting a tag message in a single driver, so keeping this
churn out of scsi_adjust_queue_depth is a clear win.

Now that the usage of scsi_adjust_queue_depth is more obvious we can
also remove all the trivial instances in ->slave_alloc or ->slave_configure
that just set it to the cmd_per_lun default.

The patch below presents a simple SCSI host lock push-down as an

with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,

and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

9a908c1aa4 [SCSI] advansys: fix narrow board error path
Error handling on advansys_board_found is fixed, because it's buggy in
the case we have an ASC_NARROW_BOARD set and failure happens on
AscInitAsc1000Driver step: it was freeing items of wrong struct in the
dvc_var union of struct asc_board, which could lead to an oops in the
case we set some of the fields in struct of narrow board as code was
choosing to always freeing wide board fields, and not everything was
being freed/released properly.
