The add_dev and remove_dev callbacks in struct class_interface currently
pass in a pointer back to the class_interface structure that is calling
them, but none of the callback implementations actually use this pointer
as it is pointless (the structure is known, the driver passed it in in
the first place if it is really needed again.)
So clean this up and just remove the pointer from the callbacks and fix
up all callback functions.

The struct class callback, class_release(), is only called in 2 places,
the pcmcia cardservices code, and in the class driver core code. Both
places it is safe to mark the structure as a const *, to allow us to
in the future mark all struct class usages as constant and move into
read-only memory.

Some classes (i.e. gpio), want to know if they have been registered or
not, and poke around in the class's internal structures to try to figure
this out. Because this is not really a good idea, provide a function
for classes to call to try to figure this out.
Note, this is racy as the state of the class could change at any moment
in time after the call is made, but as usually a class only wants to
know if it has been registered yet or not, it should be fairly safe to
use, and is just as safe as the previous "poke at the class internals"
check was.
Move the gpiolib code to use this function as proof that it works
properly.

struct class should never be modified in a sysfs callback as there is
nothing in the structure to modify, and frankly, the structure is almost
never used in a sysfs callback, so mark it as constant to allow struct
class to be moved to read-only memory.
While we are touching all class sysfs callbacks also mark the attribute
as constant as it can not be modified. The bonding code still uses this
structure so it can not be removed from the function callbacks.

Move the class code to use this structure as it is already present and

the core function call.

There's no need to manually have to set the module owner of a class, the
compiler should do it automatically for you, so add a module * to the
__class_register() function and allow it to set the module owner
automatically.
This will let us move the module pointer out of struct class eventually,
as it should not be embedded in there if we wish for it to be a
read-only structure eventually.
And, funny story, this module pointer isn't even being used for
anything, so while we will keep it around for now, it's not like it even
matters.

Instead of poking around in the struct bus_type directly for the
dev_root pointer, provide a function to return it properly reference
counted, if it is present in the bus. This will be needed to move the
pointer out of struct bus_type in the future.
Use the function in the driver core code at the same time it is
introduced to verify that it works properly.

Move the lock_class_key structure out of struct bus_type and into the
dynamic structure we create already for all bus_types registered with
the kernel. This saves on static space and removes one more writable
field in struct bus_type.
In the future, the same field can be moved out of the struct class logic
because it shares this same private structure.
Most everyone will never notice this change, as lockdep is not enabled
in real systems so no memory or logic changes are happening for them.

This reverts commit 9cbffc7a59561be950ecc675d19a3d2b45202b2b.
There are a few more issues to fix that have been reported in the thread
for the original series [1]. We'll need to fix those before this will work.
So, revert it for now.
