Pull SCSI updates from James Bottomley:
"Usual driver updates (qla2xxx, mpi3mr, mpt3sas, ufs) plus assorted
cleanups and fixes.
The biggest core change is the massive code motion in the sd driver to
remove forward declarations and the most significant change is to
enumify the queuecommand return"

attribute_container_register() has always returned 0 since its
introduction in commit 06ff5a987e ("Add attribute container to generic
device model") in the historical Linux tree [1]. Convert the return type
to void and update all callers.
This removes dead code where callers checked for errors that could never
occur.

Introduce a new structure for reporting an encrypted session over an
fc_rport. The encryption group is added as an attribute in struct
fc_rport and reports information in fc_encryption_info. This structure
contains a status member variable, which stores a bit value indicating
an encrypted session.

Current some drivers(like iscsi) call transport_register_device()
failed, they don't call transport_destroy_device() to release the
memory allocated in transport_setup_device(), because they don't
know what was done, it should be internal thing to release the
resource in register function. So fix this leak by calling destroy
function inside register function.

The transport registration may fail. Make sure the errors are propagated
to the callers.

If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any
other BUG variant in a static inline (i.e. not in a #define) then
that header really should be including <linux/bug.h> and not just
expecting it to be implicitly present.
We can make this change risk-free, since if the files using these
headers didn't have exposure to linux/bug.h already, they would have
been causing compile failures/warnings.

Let attribute group vectors be declared "const". We'd
like to let most attribute metadata live in read-only
sections... this is a start.

Every current transport class calls transport_container_release but
ignores the return value. This is catastrophic if it returns an error
because the containers are part of a global list and the next action of
almost every transport class is to free the memory used by the
container.
Fix this by making transport_container_release a void, but making it BUG
if attribute_container_release returns an error ... this catches the
root cause of a system panic much earlier. If we don't do this, we get
an eventual BUG when the attribute container list notices the corruption
caused by the freed memory it's still referencing.
Also made attribute_container_release __must_check as a reminder.

I recently tried to construct a totally generic transport class and
found there were certain features missing from the current abstract
transport class. Most notable is that you have to hang the data on the
class_device but most of the API is framed in terms of the generic
device, not the class_device.
These changes are two fold
- Provide the class_device to all of the setup and configure APIs
- Provide and extra API to take the device and the attribute class and
return the corresponding class_device

These were lost from the SCSI transport classes in
the transition to the generic classes. Ressurect it in
the generic class, since it's probable that more than SCSI
will want to use this.

Transport classes are a mechanism for providing transport specific
services to drivers that the more generic command processing layers
don't care about. A good example is the SCSI mid-layer not caring about
parallel transfer characteristics or providing services for domain
validation. Transport classes usually provide a transport specific API
at one end and a class interface at the other (for the user to
interrogate and set parameters).
Originally, transport classes were SCSI specific. However, this code is
generic to the device model. As long as you have a generic device
representing a storage interface (or device) then you can attach a
transport class to it. The new code also allows an arbitrary number of
transport classes to be attached to a device, unlike SCSI which only
allowed one. This is going to be important for things like SATA and SAS
which share the PHY layer (and hence should be capable of sharing a PHY
transport class).
The generic transport class is designed to operate identically to the
current SCSI transport classes, except that it uses generic devices
rather than SCSI devices.
We have five events:
setup
add
-----
configure
-----
remove
destroy
With callbacks for setup configure and remove.
There's also an anonymous transport class which can only respond to
configure events (and which has no attributes).
