These laptops often leave i8042 in a wierd state resulting in non-
operational touchpad and keyboard.

Commit b7802c5c1e ("Input: psmouse - use boolean type") caused the
synaptics_hardware variable to be completely useless, as it is
constantly set to 'true' throughout the whole psmouse_extensions().
This was caused by the following hunk in the commit in question
- int synaptics_hardware = 0;
+ bool synaptics_hardware = true;
which is wrong and causes driver to issue extra reset when falling
back to bare PS/2 protocol.

Even though input core tells us to restore LED state and repeat rate
at resume keyboard may be reconnected either by request from userspace
(via sysfs) or just by pulling it from the box and plugging it back in.
In these cases we still need to restore state ourselves.

We should be sending EV_LED event down to drivers upon resume even in cases
when in-kernel state of the LED is off since device could come up with some
leds turned on.

Now that input core acquires dev->event_lock spinlock and disables
interrupts when propagating input events, using spin_lock_bh() in
ff-memless driver is not allowed. Actually, the timer_lock itself
is not needed anymore, we should simply use dev->event_lock
as well.
Also do a small cleanup in force-feedback core.

There is nothing that disallows gpio-keys to share it's IRQ line
w/ other drivers. Make it use IRQF_SHARED in request_irq().
An example of other driver with which I'd like to share IRQ line
for GPIO buttons is ledtrig-gpio.

If user presses keys while i8042 is being initialized there is a chance
that keyboard data will be mistaken for results of Read Control Register
command causing futher troubles. Work around this issue by reading CTR

OQO 01+ multimedia keys produce 6x on press, e0 6x upon release.
As a result, Linux thinks that another key has been pressed (or is
repeating), when it is actually a release of the same key. Mangle the
release scancode when running on OQO so that driver recognizes it as
such.
Since the device does not have external PS/2 ports mangling is safe
since there is no chance that an external keyboard is connected.

On this model, when KBD is in active multiplexing mode, acknowledgements
to reset and get ID commands issued on KBD port sometimes are delivered
to AUX3 port (touchpad) which messes up device detection. Legacy KBC
mode works fine and since there are no external PS/2 ports on this laptop
and no support for docking station we can safely disable active MUX mode.

input_devices_seq_start() uses mutex_lock_interruptible() to acquire
the input_mutex, but doesn't properly handle the situation when the
call fails (for example due to interrupt). Instead of returning NULL
(which indicates that there is no more data) we should return
ERR_PTR()-encoded error.
We also need explicit flag indicating whether input_mutex was acquired
since input_devices_seq_stop() is called whether input_devices_seq_start()
was successful or not.
The same applies to input_handlers_seq_start().

We need to postpone restoring LED state and typematic settings until
keyboard is finished reconnecting upon resume. Normally driver core
and PM infrastructure takes care of proper ordering and dependencies,
but or case actual reconnect is done asynchronously from kseriod.
So while driver core thinks that keyboard was resumed and it is time
to let input core run it's resume handlers in reality keyboard is not
ready yet. The solution is to keep rescheduling work that adjusts LED
and rate settings until keyboard is fully enabled.

"Portable PC" in DMI so we need to add that to the DMI table as

reporting rate from 80 to 40 pps to avoid over-taxing their
