9b3a6549b2 drivers/scsi/ses.c: eliminate double free
The few lines below the kfree of hdr_buf may go to the label err_free
which will also free hdr_buf.  The most straightforward solution seems to
be to just move the kfree of hdr_buf after these gotos.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier E;
expression E1;
iterator I;
statement S;
@@

*kfree(E);
... when != E = E1
    when != I(E,...) S

0d9dc7c8b9 [SCSI] scsi_transport_fc: Fix synchronization issue while deleting vport
The issue occur while deleting 60 virtual ports through the sys
interface /sys/class/fc_vports/vport-X/vport_delete. It happen while in
a mistake each request sent twice for the same vport. This interface is
asynchronous, entering the delete request into a work queue, allowing
more than one request to enter to the delete work queue. The result is a
NULL pointer. The first request already delete the vport, while the
second request got a pointer to the vport before the device destroyed.
Re-create vport later cause system freeze.

Solution: Check vport flags before entering the request to the work queue.

1b07193b34 platform-drivers: move probe to .devinit.text in drivers/scsi
A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

fac829fdca [SCSI] raid_attrs: fix dependency problems
RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific
checking code.  This causes two problems.  Firstly if SCSI == n just
defining scsi_is_sdev_device() to return false might not be enough to
prevent gcc from emitting the code (and thus referring to undefined
symbols), so this needs surrounding with an ifdef.  Secondly, using
scsi_is_sdev_device() when SCSI is either y or m gives a subtle
problem in the m case: raid_attrs must also be m to use the symbol.
Do the usual Kconfig jiggery-pokery to fix this.
