This adds a struct eeti_ts_platform_data which currently holds only one
value to specify the interrupt polarity.
The driver has a fallback if no platform data is passed in via the
i2c_board_info, so no regression is caused.

The OLPC XO laptop incorporates a combination touchpad/tablet device
which unfortunately requires frequent recalibration. The driver will
force this automatically when various suspicious behaviors are
observed, and the user can recalibrate manually (with a special
keyboard sequence). There's currently no way, however, for an external
program to cause recalibration. We can not use the reconnect
capability which is already available in /sys because full reset of
the touchpad takes 1.1 - 1.2 secons which is too long.
This patch creates a new node in /sys which, when written with '1',
will force a touchpad recalibration; no other writes (or reads)
of this node are supported.

Properly shut off interrupts/delayed work by free-ing IRQ first
and then ensuring that enable/disable is balanced. Also add
__devinit/__devexit markings, restore poll delay/period scheduling
logic, make sure we call exit_platform_hw() method when probe
fails.

There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.
The compiler will incorrectly decide that a trivial loop like this:
unsigned char i, ...
for (i = 0; i < 128; i++) {
..
is endless, and will compile it to a single instruction that just
branches to itself.
This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.
Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
for digging through assembler differences and finding it.

I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory
leak after writing lots of data, the kmalloc-96 slab cache keeps
growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush
is never kfreed.
Commit a09485df9cda49fbde2766c86eb18a9cae585162 ("ide: move request
type specific code from ide_end_drive_cmd() to callers (v3)") and
f505d49ffd25ed062e76ffd17568d3937fcd338c ("ide: fix barriers support")
cause this regression, cmd->rq must now be set for ide_complete_cmd to
honor the IDE_TFLAG_DYN flag.

Many Nokia handsets support a Phonet interface to the cellular modem
via a vendor-specific USB interface. CDC Phonet follows the
Communications Device Class model, with one control interface, and
and a pair of inactive and active data alternative interface. The later
has two bulk endpoint, one per direction.
This was tested against Nokia E61, Nokia N95, and the existing Phonet
gadget function for the Linux composite USB gadget framework.

A pointer to mac_sonic_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

This patch allows tweaking the behaviour of GPIO_STATUS register
shift quirk that's in wm97xx-core. The problem with GPIO_STATUS
register being shifted by one doesn't appear on all hardware it
seems and causes problems with accelerated touchscreen drivers on
Palm hardware. Therefore an accelerated touchscreen driver can select
if the shift is/isn't happening on the hardware.
