 - unnecessary forward declarations in a source file
 - assignment in if condition

In addition to that the __init and __exit macros were missing at the init and

There are still two warnings left for this file related to too many leadingtabs

i do not change the functionality in any way.

The following problems are fixed:

ion_test: Add compat_ioctl support (v2)

Prior to subitting this, Colin reworked the compat_ioctl support
for the ion_test driver, moving the structure to be the same size
on both 32 and 64 bit architectures.

Two small things were left out. The compat_ioctl ptr assignment,
and the fact that despite having uniform sized types in the
structure, the structure pads out to different sizes on different
arches.

This patch resolves this issue by adding a padding entry after
the write flag, and adding the compat_ioctl ptr.

Changes in v2:
- Add a padding int rather then making write a u64

staging: ion: Avoid using rt_mutexes directly

RT_MUTEXES can be configured out of the kernel, causing compile
problems with ION.

To quote Colin:
"rt_mutexes were added with the deferred freeing feature.  Heaps need
to return zeroed memory to userspace, but zeroing the memory on every
allocation was causing performance issues.  We added a SCHED_IDLE
thread to zero memory in the background after freeing, but locking the
heap from the SCHED_IDLE thread might block a high priority allocation
thread for a long time.

The lock is only used to protect the heap's free_list and
free_list_size members, and is not held for any long or sleeping
operations.  Converting to a spinlock should prevent priority
inversion without using the rt_mutex.  I'd also rename it to free_lock
to so it doesn't get used as a general heap lock."

Thus this patch converts the rt_mutex usage to a spinlock and
renames the lock free_lock to be more clear as to its use.

I also had to change a bit of logic in ion_heap_freelist_drain()
to safely avoid list corruption.

vme: Convert VME core to register as a subsystem

Previously, VME bridge support was treated as any other driver (using
module_init() macro), but if VME bridge and vme_user (staging) drivers
were compiled into the kernel, then vme_user would attempt to register
itself before the VME core support had been loaded. This would result
in a kernel panic.

The load order of these built-in drivers is based on the order in which
drivers/staging/vme and driver/vme are compiled.

This patch changes the VME core driver to use the subsys_initcall()
macro which ensures that it is loaded before all other VME drivers
regardless of the order in which they are compiled.

staging/comedi: bug fix for module usage count on device removal

When a dynamically created comedi device is being automatically removed
by a call to `comedi_auto_unconfig()` from the lower level driver,
`comedi_device_cleanup()` is called to perform the detachment from the
lower level driver.  If the comedi device is open at the time,
`dev->use_count` will be the the number of outstanding opens.  The
function currently decrements the the module counts of the "comedi"
module and the low-level driver module by this amount and reduces
`dev->use_count` to zero.  There are various problems with this as the
`release` file operation handler `comedi_close()` also decrements
`dev->use_count` and decrements the module usage counts.  This means
that `dev->use_count` and the module counts can end up negative.

Also, the assumed one-to-one relationship between the file open count
and the low-level module usage count is invalid and can get screwed up.
We only want to stop the low-level module being unloaded while a comedi
device using the module has an open file object.

Also, there is no need to manipulate the module count of the core
"comedi" module at all since the comedi module is the owner of the file
operations structure and the system will not unload the module while
there are open file objects using it.

Correct the bugs and simplify as follows:

1. Get rid of the module count manipulations of the core "comedi" module
(`THIS_MODULE`) altogether.

2. Don't alter `dev->use_count` in `comedi_device_cleanup()` as it
should only be altered by the `open` and `release` file operation
handlers `comedi_open()` and `comedi_close()`.

3. Increment the low-level module count for the following reasons:

  a) In `comedi_open()` if the open count was zero and the comedi device
     is attached to the low-level driver.
  b) When the `COMEDI_DEVCONFIG` ioctl is used to manually attach an
     unattached comedi device to a low-level driver.  The open count
     will be greater than zero at this time.  The actual increment of
     the low-level module count is already done by
     `comedi_device_attach()`.

4. Decrement the low-level module count for the following reasons:

  a) In `comedi_close()` if the open count was 1 and the comedi device
     is attached to the low-level driver.
  b) In `comedi_device_cleanup()` (called via `comedi_auto_unconfig()`
     --> `comedi_release_hardware_device()` -->
     `comedi_free_board_dev()` when the comedi device is automatically
     unconfigured due to action by the low-level driver) if the device
     was attached (which it should be) and open count was non-zero
     (greater than zero).
  c) When the `COMEDI_DEVCONFIG` ioctl is used to manually detach the
     comedi device from the low-level driver.  The open count will be
     greater than zero at this time.

The open count should never go negative.  Parts 3 and 4 ensure that the
low-level module usage count is incremented on entering the state where
the comedi device is attached to the low-level driver AND the open count
is greater than zero, and is decremented on leaving that state.

staging/comedi: keep reference to class device after destroyed

When a dynamically allocated `struct comedi_device` gets automatically
unconfigured by a call to `comedi_auto_unconfig()` from a lower-level
driver's bus removal function (e.g. when a USB device is disconnected),
the class device in `dev->class_dev` (where `dev` points to the `struct
comedi_device`) is destroyed by a call to `device_destroy()` that
matches a previous call to `device_create()`.

However, if the `struct comedi_device` is still associated with an open
file object, the now invalid `dev->class_dev` pointer may still be
passed to `dev_printk()` (via `dev_dbg()` etc.), producing bogus output
or worse.

To fix this, call `get_device()` on the class device if
`device_create()` was successful.  Add a matching call to `put_device()`
in `comedi_dev_kref_release()` when the `struct comedi_device` is freed.
The calls to `dev_dbg()` etc. after the call to `device_destroy()` will
still produce valid output, although the device will have been
unregistered in sysfs.
