Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Two fairly small fixes: the qla one is a panic inducing use after free
and the entropy fix may seem minor but it has had huge userspace
impact thanks to an unrelated change in openssl that causes sshd to
refuse logins until it has enough entropy for the session keys, which
causes tens of minutes delay before the affected systems allow logins
after reboot"

scsi: qla2xxx: Fix panic from use after free in qla2x00_async_tm_cmd
scsi: sd: fix entropy gathering for most rotational disks
