[git pull] FireWire fixlet

[Stefan Richter <stefanr@s5r6.in-berlin.de>]

Linus,

please pull from the tag "firewire-fix" at

    git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394.git firewire-fix

to receive a one-liner fix/ revert.  This reenables WRITE SAME over SBP-2
like in v3.8...v3.12 (or v3.8-rc1...v3.13-rc2 to be overly precise).
Buggy targets which could malfunction when being subjected to this command
are already sufficiently protected by a scsi_level check in sd + SCSI core.

Subject: [PATCH] firewire: sbp2: bring back WRITE SAME support

Commit 54b2b50c20a6 "[SCSI] Disable WRITE SAME for RAID and virtual
host adapter drivers" disabled WRITE SAME support for all SBP-2 attached
targets.  But as described in the changelog of commit b0ea5f19d3d8
"firewire: sbp2: allow WRITE SAME and REPORT SUPPORTED OPERATION CODES",
it is not required to blacklist WRITE SAME.

Bring the feature back by reverting the sbp2.c hunk of commit 54b2b50c20a6.
