Subject: [GIT PULL] SCSI fixes for 5.9-rc4
Eleven fixes, mostly in drivers or minor fixes in driver related
infrastructure libraries (target, libfc and libsas). Most of the bugs
fixed only show up under rare circumstances, the exception being the
endianness problem in qla2xxx which is used as a device on some sparc
systems.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Dinghao Liu (1):
scsi: pm8001: Fix memleak in pm8001_exec_internal_task_abort
Hou Pu (1):
scsi: target: iscsi: Fix hang in iscsit_access_np() when getting tpg->np_login_sem
James Smart (4):
scsi: lpfc: Update lpfc version to 12.8.0.4
scsi: lpfc: Extend the RDF FPIN Registration descriptor for additional events
scsi: lpfc: Fix FLOGI/PLOGI receive race condition in pt2pt discovery
scsi: lpfc: Fix setting IRQ affinity with an empty CPU mask
Javed Hasan (1):
scsi: libfc: Fix for double free()
Luo Jiaxing (1):
scsi: libsas: Set data_dir as DMA_NONE if libata marks qc as NODATA
René Rebe (1):
scsi: qla2xxx: Fix regression on sparc64
Tomas Henzl (2):
scsi: mpt3sas: Don't call disable_irq from IRQ poll handler
scsi: megaraid_sas: Don't call disable_irq from process IRQ poll
Varun Prakash (1):
scsi: target: iscsi: Fix data digest calculation
