We don't actually care if the device has been runtime suspended immediately
so we can just drop the reference without waiting for any state change to
be implemented. This may allow us to avoid some suspend/resume cycles and
is a bit more friendly to the rest of the system.

Convert the driver to standard spilt model arch-specific code registers
platform device to which driver code can bind later.
Also request IRQ immediately upon binding to the device instead of doing
this when serio port is being opened.

Also make 'open' a bool since it is really a boolean.

Because we are using platform_device_probe() to register the driver
we do not need to assign driver's probe method. We also can mark
ske_keypad_probe(), together with ske_keypad_chip_init(), as __init
instead of __devinit.

This calculation determines the physical dimensions of the tablet,
used later on in calculate_touch_res to obtain the touch sensor
resolution.
Instead of dividing the logical size by the resolution, the current
code performs a multiplication. This doesn't pose a problem for the
3rd-gen Bamboo since the resolution and scale factor happen to be
identical, but will produce an incorrect result for other cases.

Pull xen updates from Konrad Rzeszutek Wilk:
"which has three neat features:
- PV multiconsole support, so that there can be hvc1, hvc2, etc; This
can be used in HVM and in PV mode.
- P-state and C-state power management driver that uploads said power
management data to the hypervisor. It also inhibits cpufreq
scaling drivers to load so that only the hypervisor can make power
management decisions - fixing a weird perf bug.
There is one thing in the Kconfig that you won't like: "default y
if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it
all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by
default is off). I've a fix to convert that boolean expression
into "default m" which I am going to post after the cpufreq git
pull - as the two patches to make this work depend on a fix in Dave
Jones's tree.
- Function Level Reset (FLR) support in the Xen PCI backend.
Fixes:
- Kconfig dependencies for Xen PV keyboard and video
- Compile warnings and constify fixes
- Change over to use percpu_xxx instead of this_cpu_xxx"
Fix up trivial conflicts in drivers/tty/hvc/hvc_xen.c due to changes to
a removed commit.

PV-on-HVM guests may want to use the xen keyboard/mouse frontend, but
they don't use the xen frame buffer frontend. For this case it doesn't
make much sense for INPUT_XEN_KBDDEV_FRONTEND to depend on
XEN_FBDEV_FRONTEND. The opposite direction always makes more sense, i.e.
if you're using xenfb, then you'll want xenkbd. Switch the dependencies.

As part of the removal of get_driver()/put_driver(), this patch
(as1510) changes driver_find(); it now drops the reference it acquires
before returning. The patch also adjusts all the callers of
driver_find() to remove the now unnecessary calls to put_driver().
In addition, the patch adds a warning to driver_find(): Callers must
make sure the driver they are searching for does not get unloaded
while they are using it. This has always been the case; driver_find()
has never prevented a driver from being unregistered or unloaded.
Hence the patch will not introduce any new bugs. The existing callers
all seem to be okay in this respect, however I don't understand the
video drivers well enough to be certain about them.

ALPS touchpad detection fails if some buttons of ALPS are pressed.
The reason is that the "E6" query response byte is different from

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

Some bcm5974 trackpads have a physical button beneath the physical surface.
This patch sets the property bit so user space applications can detect the
trackpad type and act accordingly.

If serio_raw_write was always returning number of bytes successfully
sent to serio port and never signalled error condition to the caller.
Change it so that for completely failed transfers appropriate error
code returned to the caller (partially successful writes still return
number of bytes transferred).

Recent conversion to module_platform_driver() went a bit too far and
converted not only drivers that used platform_driver_register() but
also ones using platform_driver_probe(), breaking them in process.

Drivers shouldn't use NO_IRQ. Microblaze and PPC
define NO_IRQ as 0 and this reference will be removed
in near future.

Several protocol initialization routines can fail after they set up
psmouse methods, such as reconnect and disconnect. This may lead to
these stale methods used with different protocol that they were
intended to be used for and may cause unpredictavle behavior and/or
crashes.
Make sure we start with a clean slate before executing each and every
protocol detection and/or initialization routine.

If there is a full packet in the buffer, and we overflow that buffer
right after checking for that condition, it would have been possible
for us to block indefinitely (rather, until the next full packet) even if
the file was marked as O_NONBLOCK.

Without this, it was possible for the reader to get ahead of packet_head.
If the input device generated a partial packet *right* after the reader
got ahead, then we can get into a situation where the device is marked
readable, but read always returns 0 until the next packet is finished
(i.e a SYN is generated by the input driver).
This situation can also happen if we overflow the buffer while a reader
is trying to read an event out.
