We need to call platform_device_unregister(i8042_platform_device)
before calling platform_driver_unregister() because i8042_remove()
resets i8042_platform_device to NULL. This leaves the platform device
instance behind and prevents driver reload.

By visual inspection, the reported touch_major and touch_minor axes
are a factor of two too small. Presumably the device actually reports
the semi-major and semi-minor axes. Corrected with this patch.

For MT slots, the ABS_MT_TRACKING_ID determines whether a slot is in use,
but currently leaves initialization up to the drivers. This patch sets the
slot state to unused upon creation.

This fixes a regression introduced in
3b57ca0f80.
The data[6] byte contains either 1 or -1 depending on the whether the
mouse wheel on older wacom tablets is moved down (1) or up (-1). The
patch introduced in the above commit changed the cast from (signed char)
to (signed). When cast as a signed integer and negated, the value of -1
(stored in the byte as 0xff) became -255 rather than 1. This patch
reverts the cast to a (signed char) and also removes an unnecessary
(signed) cast, as all the values operated on are bitmasked.

Recent modprobe and udev versions allow to create device nodes
for modules which are not loaded. Only the first access will cause
the in-kernel module loader to pull-in the module. Systems which
never access the device node will not needlessly load the module,
and no longer need init scripts or other facilities to unconditionally
load it.

They've been introduced by 987a6c02 ("Input: switch to input_abs_*()
access functions") and they appear to be some kind of debug left-over.
[Dmitry Torokhov: these are my fault - I added XX prefixes in places where
I wanted to do additional review of the code but failed to actually do
that in these particular instances.]

To keep panic_timeout accuracy when running under a hypervisor, the
current implementation only spins on long time (1 second) calls to mdelay.
That brings a good effect, but the problem is the keyboard LEDs don't
blink at all on that situation.
This patch changes to call to panic_blink_enter() between every mdelay and
keeps blinking in spite of long spin timer mode.
The time to call to mdelay is now 100ms. Even this change will keep
panic_timeout accuracy enough when running under a hypervisor.

While the original problem only caused a slight disturbance on the
