Subject: [GIT PULL] SCSI fixes for 3.3-rc4
This is a set of assorted bug fixes for power management, mpt2sas, ipr,
the rdac device handler and quite a big chunk for qla2xxx (plus a use
after free of scsi_host in scsi_scan.c).
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-rc-fixes-2.6.git scsi-fixes
The short changelog is
Alan Stern (1):
scsi_pm: Fix bug in the SCSI power management handler
Alexey Khoroshilov (1):
mpt2sas: Fix mismatch in mpt2sas_base_hard_reset_handler() mutex lock-unlock
Andrew Vasquez (4):
qla2xxx: Correct out of bounds read of ISP2200 mailbox registers.
qla2xxx: Remove errant clearing of MBX_INTERRUPT flag during CT-IOCB processing.
qla2xxx: Clear options-flags while issuing stop-firmware mbx command.
qla2xxx: Add an "is reset active" helper.
Arun Easi (1):
qla2xxx: Propagate up abort failures.
Chad Dupuis (2):
qla2xxx: Update version number to 8.03.07.13-k.
qla2xxx: Add check for null fcport references in qla2xxx_queuecommand.
Dave Jiang (1):
isci: Fix NULL ptr dereference when no firmware is being loaded
Giridhar Malavali (2):
qla2xxx: Proper detection of firmware abort error code for ISP82xx.
qla2xxx: Complete mailbox command timedout to avoid initialization failures during next reset cycle.
Huajun Li (1):
scsi_scan: Fix 'Poison overwritten' warning caused by using freed 'shost'
Kleber Sacilotto de Souza (1):
ipr: fix eeh recovery for 64-bit adapters
Michael Christie (1):
qla2xxx: Remove check for null fcport from host reset handler.
Moger, Babu (1):
scsi_dh_rdac: Fix for unbalanced reference count
Shyam Sundar (1):
qla2xxx: Remove resetting memory during device initialization for ISP82xx.
