2017-12-07scsi: devinfo: apply to HP XP the same flags as Hitachi VSPXose Vazquez Perez1-1/+1
Commit 56f3d383f37b ("scsi: scsi_devinfo: Add TRY_VPD_PAGES to HITACHI OPEN-V blacklist entry") modified some Hitachi entries: HITACHI is always supporting VPD pages, even though it's claiming to support SCSI Revision 3 only. The same should have been done also for HP-rebranded.

Commit 627511e3e675 ("[SCSI] scsi_devinfo: update Hitachi entries (v2)") modified some Hitachi entries: Four models, OPEN-/DF400/DF500/DISK-SUBSYSTEM, can handle REPORT_LUN, and the BLIST_REPORTLUN2 flag needs to be set. And DF600 doesn't require any flags because it returns ANSI 03h (SPC). The same should have been done also for HP counterparts.

2017-12-07scsi: qla2xxx: Fix memory leak in dual/target modehimanshu.madhani@cavium.com2-11/+11
When driver is loaded in Target/Dual mode, it creates QPair to support MQ and allocates resources for each QPair. This Qpair initialization is delayed until the FW personality is changed to Dual/Target mode by issuing chip reset. At the time of chip reset firmware is re-initilized in correct personality all the QPairs are initialized by sending MBC_INITIALIZE_MULTIQ (001Fh). This patch fixes memory leak by adding check to issue MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the flag is set for initiator mode, and clean up QPair resources correctly during the driver unload. This MBX does not need to be issued for Target/Dual mode because chip reset will reset ISP.
