[PATCH 10/11] input: keyboard: gpio_keys: convert platform driver to use dev_groups

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

Platform drivers now have the option to have the platform core create
and remove any needed sysfs attribute files.  So take advantage of that
and do not register "by hand" a bunch of sysfs files.
