The support of the Moorestown was removed [1] from kernel long time ago. This
is just a follow up of that change.

If the driver was compiled with DMA support, but DMA channels weren't acquired
by some reason, mid_spi_dma_exit() will crash the kernel.

Pull x86 platform driver updates from Matthew Garrett:
 "A moderate number of changes, but nothing awfully significant.

  A lot of const cleanups, some reworking and additions to the rfkill
  quirks in the asus driver, a new driver for generating falling laptop
  events on Toshibas and some misc fixes.

  Maybe vendors have stopped inventing things"

Pull file locking bugfixes from Jeff Layton:
 "Most of these patches are to fix a long-standing regression that crept
  in when the BKL was removed from the file-locking code.  The code was
  converted to use a conventional spinlock, but some fl_release_private
  ops can block and you can end up sleeping inside the lock.

  There's also a patch to make /proc/locks show delegations as 'DELEG'"

* tag 'locks-v3.17-2' of git://git.samba.org/jlayton/linux:
  locks: update Locking documentation to clarify fl_release_private behavior
  locks: move locks_free_lock calls in do_fcntl_add_lease outside spinlock
  locks: defer freeing locks in locks_delete_lock until after i_lock has been dropped
  locks: don't reuse file_lock in __posix_lock_file
  locks: don't call locks_release_private from locks_copy_lock
  locks: show delegations as "DELEG" in /proc/locks

Pull aio updates from Ben LaHaise.

* git://git.kvack.org/~bcrl/aio-next:
  aio: use iovec array rather than the single one
  aio: fix some comments
  aio: use the macro rather than the inline magic number
  aio: remove the needless registration of ring file's private_data
  aio: remove no longer needed preempt_disable()
  aio: kill the misleading rcu read locks in ioctx_add_table() and kill_ioctx()

This driver adds support for the built-in accelereometer found
on recent Toshiba laptops with HID TOS620A.

This driver receives ACPI notify events 0x80 when the sensor
detects a sudden move or a harsh vibration, as well as an
ACPI notify event 0x81 whenever the movement or vibration has
been stabilized.

Also provides sysfs entries to get/set the desired protection
level and reseting the HDD protection interface.

Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.

This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.
