| * 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.

* | [SCSI] qla4xxx: correctly update session discovery_parent_idx.Manish Rangankar2013-10-251-19/+180
|/ | | | | | | | | | | | Earlier logic for driver created iscsi_session->discovery_parent_idx was to store ram index of a sendtarget entry, but driver frees sendtarget ram index as soon as firmware is done with discovery, which is available for further use. So changing the logic to point iscsi_session->discovery_parent_idx to store sendtarget flashnode index.

FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.
