scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function

2018-01-01T20:50:48+00:00

commit 5c756065e47dc3e84b00577bd109f0a8e69903d7 upstream.

Internal error codes happen to be positive, thus the PCI driver core
won't treat them as failure, but we do. This would cause a crash later
on as lpfc_pci_remove_one() is called (e.g. as shutdown function).

scsi: lpfc: Add shutdown method for kexec

2017-07-18T17:38:30+00:00

commit 85e8a23936ab3442de0c42da97d53b29f004ece1 upstream.

We see lpfc devices regularly fail during kexec. Fix this by adding a
shutdown method which mirrors the remove method.

lpfc: fix misleading indentation

2016-04-30T22:05:20+00:00

commit aeb6641f8ebdd61939f462a8255b316f9bfab707 upstream.

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.

scsi: Fix up files implicitly depending on module.h inclusion

2011-10-31T23:31:24+00:00

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway.  We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

scsi: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:31:23+00:00

For the basic SCSI infrastructure files that are exporting symbols
but not modules themselves, add in the basic export.h header file
to allow the exports.

[SCSI] lpfc 8.3.27: Fix queue allocation failure recovery

2011-10-16T16:32:17+00:00

Fix queue allocation failure recovery

- Move the allocation of the Queues closer to the creation of the queues.
- If there is a problem with creation, or if the HBA is reset, the queues
  will be completely freed and re allocated.
- Only allocate fcp_eq_hdl if cfg_fcp_eq_count is non-zero.
