Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Six fixes, all in drivers.
The biggest are the UFS devfreq fixes which address a lock inversion
and the two iscsi_tcp fixes which try to prevent a use after free from
userspace still accessing an area which the kernel has released (seen
by KASAN)"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: device_handler: alua: Remove a might_sleep() annotation
scsi: iscsi_tcp: Fix UAF during login when accessing the shost ipaddress
scsi: iscsi_tcp: Fix UAF during logout when accessing the shost ipaddress
scsi: ufs: core: Fix devfreq deadlocks
scsi: hpsa: Fix allocation size for scsi_host_alloc()
scsi: target: core: Fix warning on RT kernels
