Enable button release event redirection to the device that got the
button press not only for touchpads with interleaved protocols, but
unconditionally for all Alps touchpads. This is required at least
for the touchpads in Dell Inspiron 8200 and Latitude d630.

Now that the WM831x core has been converted to use genirq for the
interrupt controller there is no need for the client drivers to
use a WM831x-specific API rather than just calling genirq directly.

Also fixes a leak of the IRQ during init failure - the error path
free_irq() was using NULL rather than the driver data as the data
pointer so free_irq() wouldn't have matched.

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.

The time interval between consecutive interrupts depends on a number of
tunables: first_conversion_delay, acquisition_time, averaging and foremost
the pen_down_acc_interval.

Since the mod_timer() action for the PEN UP event happens in the
spi_async() callback function, latencies incurred by the spi bus drivers
also need to be taken into account.

So all in all, give the PEN UP event a bit more wiggle room and increase
timeout to 100ms.

The AD7873 is almost identical to the ADS7846; the only difference is
related to the Power Management bits PD0 and PD1.  This results in a
slightly different PENIRQ enable behavior.  For the AD7873, VREF should
be turned off during differential measurements.

So, add the AD7873/43 to the list of driver supported devices, and prevent
VREF usage during differential/ratiometric conversion modes.

We need to use the nosync version of disable_irq so that we don't hang in
the IRQ handler as we don't ACK the interrupt until later.  This used to
work regardless, but at some point, the IRQ behavior changed.  Not sure

Holding the BKL in input_open_file seems pointless because it does not
protect against updates of input_table, and all open functions from the
underlying drivers have proper mutex locking.

This makes input_open_file take the input_mutex when accessing
the table and no lock when calling into the lower function.

of atkbd driver. Now that the driver has been switched to use unsigned
short keycodes instead of unsigned char we can release this range back
into pull. We keep code 255 (ATKBD_KEY_NULL) reserved since users may
have been using it to silence keys they do not care about since atkbd
silently drops scancodes mapped to this keycode.

When polled input device is opened and closed and there are no other
users of polled device, the workqueue is created and destroyed in
every open / close operation. It is probable that at some point
dynamic allocation of internal parts of the workqueue cause changes to the
workqueue.

When a work is queued to the workqueue the work struct contains pointers
to the workqueue data. If the workqueue has been changed and the work
has never been queued to the new workqueue, work-struct contains pointers
to the non-existing workqueue. This will cause crash at the work
cancellation during device close since cancellation of a work assumes
that the workqueue exists.

To prevent that, work struct is cleaned up at device close. This keeps
work struct clean for the next use.
