Turns out that multiple people sent pretty much the same patch
for the same staging drivers. Commit these in two different
branches and merge them together to get a more complete coverage
of the cleanup and properly credit everyone for the work that they
did.

This fixes some code style issues like to add one space after a while or
switch statement and before a open parenthesis '(', and to include KERN_

the code was looping, setting s_move[i] to the following calculations
if (actual_step>= 0)
s_move[i] = ((((i + 1) * gain + 0x200) - (i * gain + 0x200)) / 0x400);
else
s_move[i] = ((((i + 1) * gain - 0x200) - (i * gain - 0x200)) / 0x400);
but, this code reduces to the expression
s_move[i] = gain>> 10;
The reason for the complexity was to generate a step function with
integer division and rounding to land on specific values. But these calculations
can be simplified to the following code:
gain = ((actual_step<< 10) / 5)>> 10;
for (i = 0; i<= 4; i++)
s_move[i] = gain;

This was done using a semantic patch (http://coccinelle.lip6.fr/) that
checks that the declaration is not inside a function definition, that the
defined variable is not exported using EXPORTED_SYMBOL, etc, and that the
defined variable does not occur in any other file. If these conditions
hold, static is added before the declaration.

Support for input devices connected to GPIO pins. This adds support
for HTC Dream's keyboard and its trackball. Generic support already
exists for keyboard on GPIO, but this one is more advanced because it
can detect shadow key presses (and actually works with Dream :-).
(It also contains Kconfig/Makefile changes, including some that were
missing from previous commit. Sorry.)

In vfe_send_msg_no_payload there is a wrong struct vfe_message allocation.
It allocates only sizeof(pointer to vfe_message) for a whole structure.

This is first part of touchscreen cleanups. I did not remove
earlysuspend functionality for now (to help Google merge the changes).
I mainly introduced helpers to reduce code duplication, and split huge
functions into smaller ones.

This adds support for synaptic touchscreen, used in HTC dream
cellphone.
This is original version from Arve, fixed only to compile; I do have
cleaner version, but I broken something inside, and this will preserve
authorship better. I originally tried to push the driver directly to
input/touchscreen, but the driver has some issues with interrupt
handling that are more difficult to fix than I expected at first.

This patch adds driver for HTC Dream camera. I guess driver is
slightly higher quality than usual for staging/ , but it is fairly big
and I don't feel like doing all the cleanups myself. Also some parts
can probably be removed, as they did not end up in shipping hardware..

Infrastructure to support the Qualcomm "shared memory driver"
interface, used to communicate with the baseband processor on MSM7k
SoCs. The smd core provides low level facilities to interact with the
shared memory comms region, and a "virtual serial channel" interface
that higher level transports (AT command channel, rmnet virtual
ethernet, qmi network management protocol, and oncrpc, for example)
are routed over.
