Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Two simple fixes, both of which cause I/O hangs.
The storvsc one is from the hyper-v which can hang under certain hot
add/remove conditions and the other is generally, where removing a
target and a device in close proximity can result in the release
method being executed twice (and subsequent list and other corruption
and an eventual panic)"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: storvsc: Fix scsi_cmd error assignments in storvsc_handle_error
scsi: core: check for device state in __scsi_remove_target()
