[PATCH] input: make gpio-keys use IRQF_SHARED

[Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>]

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.
