This fixes a regression introduced by the dynamic allocation of absinfo
for input devices. We need to bail out early for input devices which
don't have absolute axis.

[<ffffffff81328176>] usb_autopm_get_interface+0x26/0x60
[<ffffffffa02bc626>] wacom_open+0x36/0x90 [wacom]
wacom_open() takes wacom->lock and calls usb_autopm_get_interface(),
which in turn calls wacom_resume() which tries to acquire the lock
again.
The fix is to call usb_autopm_get_interface() first, before we take
the lock.
Since we do not do usb_autopm_put_interface() until wacom_close()
is called runtime PM is effectively disabled for the driver, however
changing it now would risk regressions so the complete fix will
have to wait till the next merge window.

The input devices created by uinput do not currently handle multitouch
properly. All events will appear as if they came from slot zero, and
the input event buffers are not adjusted. This patch creates the MT
slots during setup, and sets the number of events per packet based
on the MT usage.

We need to call platform_device_unregister(i8042_platform_device)
before calling platform_driver_unregister() because i8042_remove()
resets i8042_platform_device to NULL. This leaves the platform device
instance behind and prevents driver reload.

This fixes a regression introduced in
3b57ca0f80c5c8994b5b1e3d3f904cfe727951f2.
The data[6] byte contains either 1 or -1 depending on the whether the
mouse wheel on older wacom tablets is moved down (1) or up (-1). The
patch introduced in the above commit changed the cast from (signed char)
to (signed). When cast as a signed integer and negated, the value of -1
(stored in the byte as 0xff) became -255 rather than 1. This patch
reverts the cast to a (signed char) and also removes an unnecessary
(signed) cast, as all the values operated on are bitmasked.

for modules which are not loaded. Only the first access will cause
the in-kernel module loader to pull-in the module. Systems which
never access the device node will not needlessly load the module,

To keep panic_timeout accuracy when running under a hypervisor, the
current implementation only spins on long time (1 second) calls to mdelay.
That brings a good effect, but the problem is the keyboard LEDs don't
blink at all on that situation.
This patch changes to call to panic_blink_enter() between every mdelay and
keeps blinking in spite of long spin timer mode.
The time to call to mdelay is now 100ms. Even this change will keep
panic_timeout accuracy enough when running under a hypervisor.

This is more kernel-ish, saves some space, and also allows us to
expand the ops without breaking all the callers who are happy for the
new members to be NULL.
The few places which defined their own param types are changed to the
new scheme (more which crept in recently fixed in following patches).
Since we're touching them anyway, we change get() and set() to take a
const struct kernel_param (which they really are). This causes some
harmless warnings until we fix them (in following patches).
To reduce churn, module_param_call creates the ops struct so the callers
don't have to change (and casts the functions to reduce warnings).
The modern version which takes an ops struct is called module_param_cb.

According to the Dell/Ubuntu driver, what was previously observed as
"jumpy cursor" corresponds to the hardware sending incorrect data for
the first two reports of a one touch finger. So let's use the same
workaround as in the other driver. Also, detect another firmware
version with the same behaviour, as in the other driver.

Allow platform code to specify callbcks that will be invoked when
input device is opened or closed, allowing, for example, to enable
the device.

Split ioctl handling into 3 separate sections: fixed-length ioctls,
variable-length ioctls and multi-number variable length handlers.
This reduces identation and makes the code a bit clearer.

As all callers are now changed to only use the input_abs_*() access
helpers, switching over to dynamically allocated ABS information is
easy. This reduces size of struct input_dev from 3152 to 1640 on
64 bit architectures.

Change all call sites in drivers/input to not access the ABS axis
information directly anymore. Make them use the access helpers instead.
Also use input_set_abs_params() when possible.
Did some code refactoring as I was on it.

The kpad structure is assigned to i2c client via i2s_set_clientdata()
at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to
access it (via dev_get_drvdata! which is not nice at all) causing an
oops.
Let's pass pointer to kpad directly into adp5588_gpio_add() and
adp5588_gpio_remove() to avoid accessing driver data before it is
set up.
Also split out building of gpiomap into a separate function to
clear the logic.

ixp4xx_spkr_interrupt is not a timer interrupt and therefore should
not use IRQF_TIMER. Use the recently introduced IRQF_NO_SUSPEND
instead since that is the actual desired behaviour.
