USB: convert drivers/input/* to use module_usb_driver()
This converts the drivers in drivers/input/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

Revert "Input: appletouch - fix integer overflow issue"
This reverts commit 04b4b88cca0ebe3813b4b6f014fb6a0db380b137.
While the original problem only caused a slight disturbance on the
edge of the touchpad, the commit above to "fix" it completely breaks
operation on some other models such as mine.
We'll sort this out separately, revert the patch for now.

USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,
usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()
They should only be used in code which really needs DMA coherency.
All call sites have been changed accordingly, except for staging
drivers.

Input: appletouch - fix integer overflow issue
When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
PowerBooks the driver was casting X and Y coordinates values to
'signed char'. Testing on one of such PowerBooks I have noticed that
touchpad always generates positive values, but some of them are greater
that 127, and thus, when cast to 'signed char' being interpreted as
a negative.
Such bigger values have been observed infrequently, closer to the
edges of a touchpad, so the problem was not very visible.
Nevertheless, the patch would potentially improve touchpad
driver accuracy.

Jeremy Huddleston <jeremyhu@freedesktop.org> |
Input: appletouch - improve finger detection
The appletouch driver is prone to reporting multiple fingers when only
one is pressing. The appletouch driver queries an array of pressure
sensors and counts local maxima in pressure to determine the number of
fingers. It just does this on the raw values, so a data stream like:
0 100 250 300 299 300 250 100 0
actually registers as 2 fingers.
This patch updates the logic to ignore small dips in pressure that are
less than the threshold.

Stelian Pop <stelian@popies.net> |
Input: appletouch - driver refactoring
The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.
This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.
As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

Input: appletouch - apply idle reset logic to all touchpads
Not only Geyser 3 but also Geyser 1 need to be reset after they become
idle to stop them from needlessly waking up the kernel. Do idle reset
on all touchpads, regardless of their version - if we see 10 empty
packets the touchpad needs to be reset; good touchpads should not send
empty packets anyway.

Input: appletouch - improve powersaving for Geyser3 devices
The appletouch geyser3 devices found in the Intel Macs (and possibly
some later PPC ones?) send a constant stream of packets after the first
touch. This results in the kernel waking up around once every couple of
milliseconds to process them, making it almost impossible to spend any
significant amount of time in C3 state on a dynamic HZ kernel. Sending
the mode initialization code makes the device shut up until it's touched
again. This patch does so after receiving 10 packets with no interesting
content.
