This reverts commit 86b84167 as it introduced a
VID/PID conflict with its original owner: hid-wiimote got
hid:b0005g*v0000054Cp00000306 added but hid-sony already has this id for the
PS3 Remote (and the ID is oficically assigned to Sony).

Revert the commit to avoid hid-sony regression. David is working on a
bluez patch to force proper ID on the wiimote.

The ff_memless has a timer running which gets run in an atomic context and
calls the play_effect callback. The callback function for sony uses the
hid_output_raw_report (overwritten by sixaxis_usb_output_raw_report) function
to handle differences in the control message format. It is not safe for an
atomic context because it may sleep later in usb_start_wait_urb.

This "scheduling while atomic" can cause the system to lock up. A workaround is
to make the force feedback state update using work_queues and use the
play_effect function only to enqueue the work item.

We moved minor deallocation to drm_dev_free() in:
  commit 8f6599da
  Author: David Herrmann <dh.herrmann@gmail.com>
  Date:   Sun Oct 20 18:55:45 2013 +0200

      drm: delay minor destruction to drm_dev_free()

However, this causes a call to drm_unplug_minor(), which should just do
nothing as drm_dev_unregister() already called this.

But a separate patch caused kdev lifetime changes:
  commit 5bdebb18
  Author: Dave Airlie <airlied@redhat.com>
  Date:   Fri Oct 11 14:07:25 2013 +1000

      drm/sysfs: sort out minor and connector device object lifetimes.

Thus making our dev_is_registered() call useles (and even segfault if it
is NULL). Replace it with a simple !kdev test and we're fine.

Also display a message in the alert handler if the condition
is encountered.

Even though not all overtemperature conditions cause ALERT
to be set, we should not ignore them in the alert handler.

This reverts commit 5beea882 as it
breaks trackpoint operation on XT2.

This patch enhances the type safety for the kfifo API.  It is now safe
to put const data into a non const FIFO and the API will now generate a
compiler warning when reading from the fifo where the destination
address is pointing to a const variable.

As a side effect the kfifo_put() does now expect the value of an element
instead a pointer to the element.  This was suggested Russell King.  It
make the handling of the kfifo_put easier since there is no need to
create a helper variable for getting the address of a pointer or to pass
integers of different sizes.

IMHO the API break is okay, since there are currently only six users of
kfifo_put().

The code is also cleaner by kicking out the "if (0)" expressions.

On architectures where long is more then 32 bits, modifying a 32-bit field
with set_bit (and other atomic bit operations) may cause bytes following
the field to by modified.

Because the endianness of the bits within a field is the native endianness
of the CPU[1], on big-endian machines, bit number zero is in the last byte
of the field.

Therefore, `set_bit(0, ptr)' on a 64-bit big-endian machine is roughly
equivalent to `((char *)ptr)[7] |= 1', and since w1 driver uses a 32-bit
field for holding the flags, this causes bytes beyond the field to be
modified.

[1] From Documentation/atomic_ops.txt:

    Native atomic bit operations are defined to operate on objects
    aligned to the size of an "unsigned long" C data type, and are
    least of that size.  The endianness of the bits within each
    "unsigned long" are the native endianness of the cpu.
