Subject: [GIT PULL] SCSI fixes for 4.12-rc1
This is the first sweep of mostly minor fixes. There's one security
one: the read past the end of a buffer in qedf, and a panic fix for
lpfc SLI-3 adapters, but the rest are a set of include and build
dependency tidy ups and assorted other small fixes and updates.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Bart Van Assche (1):
scsi: scsi_lib: Add #include <scsi/scsi_transport.h>
Christoph Hellwig (1):
scsi: MAINTAINERS: update OSD entries
Colin Ian King (2):
scsi: pmcraid: remove redundant check to see if request_size is less than zero
scsi: lpfc: ensure els_wq is being checked before destroying it
Dan Carpenter (2):
scsi: qedf: Cleanup the type of io_log->op
scsi: lpfc: double lock typo in lpfc_ns_rsp()
Guenter Roeck (1):
scsi: cxlflash: Select IRQ_POLL
Gustavo A. R. Silva (1):
scsi: qedf: properly update arguments position in function call
Hannes Reinecke (1):
scsi: libfc: do not flood console with messages 'libfc: queue full ...'
James Smart (1):
scsi: lpfc: Fix panic on BFS configuration
Kees Cook (1):
scsi: qedf: Avoid reading past end of buffer
Zhou Zhengping (1):
scsi: Skip deleted devices in __scsi_device_lookup
