* scsi: bfa: turn bfa_mem_{kva,dma}_setup into inline functionsArnd Bergmann2016-11-221-13/+17

* scsi: fc: Export fc_bsg_jobdone and use it in FC driversJohannes Thumshirn2016-11-181-2/+4
| | | | | | | | | | | | | | | | Export fc_bsg_jobdone so drivers can use it directly instead of doing the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs. That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done. As we've converted all LLDDs over to use fc_bsg_jobdone() directly, we can remove the function pointer from struct fc_bsg_job as well.

* scsi: don't set tagging state from scsi_adjust_queue_depthChristoph Hellwig2014-11-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [SCSI] bfa: Chinook quad port 16G FC HBA claim issueVijaya Mohan Guvva2013-12-181-2/+4
|/ | | | | | | | | | | | | | | | Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check. This patch includes changes to read the right firmware for quad port chinook.

* [SCSI] bfa: Fix crash when symb name set for offline vportVijaya Mohan Guvva2013-12-033-8/+14
| | | | | | | | | | This patch fixes a crash when tried setting symbolic name for an offline vport through sysfs. Crash is due to uninitialized pointer lport->ns, which gets initialized only on linkup (port online).

| * SCSI: remove unnecessary pci_set_drvdata()Jingoo Han2013-10-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.
