gcc-6.0 warnings for scsi

gcc-6.0 warnings for scsi

[Arnd Bergmann]

gcc-6 found a couple of bugs in scsi drivers that are not
yet fixed in linux-next.

In all three cases, the code is indented in a rather misleading
way, but actually correct. I think it would be good to have
this fixed in 4.6, but no backports are needed even though
the problems have all been around for a while.

[PATCH 1/3] aacraid: add missing curly braces

[Arnd Bergmann]

gcc-6 warns about obviously wrong indentation for newly added
code in aac_slave_configure():

drivers/scsi/aacraid/linit.c: In function 'aac_slave_configure':
drivers/scsi/aacraid/linit.c:458:3: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
   sdev->tagged_supported = 1;
   ^~~~
drivers/scsi/aacraid/linit.c:455:4: note: ...this 'else' clause, but it is not

gcc is correct, and evidently this was meant to be within the curly
braces that should have been there to start with. This patch adds
them, which avoids the warning and makes it clear what was intended
here.

Nothing changes in behavior because in the 'if' block, the
sdev->tagged_supported flag is known to be set already.

[PATCH 2/3] lpfc: fix misleading indentation

[Arnd Bergmann]

gcc-6 complains about the indentation of the lpfc_destroy_vport_work_array()
call in lpfc_online(), which clearly doesn't look right:

drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_online':
drivers/scsi/lpfc/lpfc_init.c:2880:3: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]
   lpfc_destroy_vport_work_array(phba, vports);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/lpfc/lpfc_init.c:2863:2: note: ...this 'if' clause, but it is not
  if (vports != NULL)
  ^~

Looking at the patch that introduced this code, it's clear that the
behavior is correct and the indentation is wrong.

This fixes the indentation and adds curly braces around the previous
if() block for clarity, as that is most likely what caused the code
to be misindented in the first place.

[PATCH 3/3] megaraid_sas: add missing curly braces in ioctl handler

[Arnd Bergmann]

gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl
function:

drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl':
drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by... [-Wmisleading-indentation]

drivers/scsi/megaraid/megaraid_sas_base.c:6653:3: note: ...this 'if' clause, but it is not
   if (kbuff_arr[i])
   ^~

The code is actually correct, as there is no downside in clearing a NULL
pointer again.

This clarifies the code and avoids the warning by adding extra curly
braces.

Nope.

vports is only valid from within the indentation block, so it should
be moved into it.

Well, every other user of the function also looks like

	vports = lpfc_create_vport_work_array(phba);
	if (vports != NULL) {
		do_something(vports);
	}
	lpfc_destroy_vport_work_array(phba, vports);

and lpfc_destroy_vport_work_array() does nothing if its argument is NULL.

I still think my patch is the correct fix for the warning.

Actually the lpfc code is inconsistent about whether the _destroy call
is within the (vports != NULL) test or not, but as you say below it
doesn't matter.
