Since 43cc71ee, the platform modalias
is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable
"input" platform drivers, to re-enable auto loading.

Cleanup IRQ handling in gpio_keys:  bail after handling the IRQ, and
report IRQ_NONE if we never handle it.

Currently, gpio_keys.c assumes the GPIOs to be already properly configured;
this patch changes gpio-keys to perform explicit calls to gpio_request() and
gpio_configure_input().

This matches the behaviour of leds-gpio.

get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

As David Brownell pointed out, gpio_keys driver does not check
return code of gpio_to_irq().

This patch adds the gpio_to_irq return code check to gpio_keys
and moves the IRQ edge type setting to request_irq flags to avoid
changing the irq type before we have confirmed we can use it.

The gpio_keys driver is wrongly ARM-specific; it can't build on
other platforms with GPIO suport.  This fixes that problem.

This is an interrupt-driven keyboard driver for simple buttons
connected directly to CPU GPIO lines of embedded ARM systems.
It supports pxa architectures and is used by a number of PDAs
and PocketPC phones in the handhelds.org kernel. Support for
other architectures, such as sa11xx and sc2410, will be added
once generic GPIO API is available.
