The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Switch over to using olpc-ec.h in multiple steps, so as not to break builds.
This covers every driver that calls olpc_ec_cmd().

The XO-1 rfkill driver should only send EC commands when changing
between blocked/unblocked state.
The rfkill switch is asked to be unblocked on every resume (even when
the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET
command here upsets the resume sequence of the libertas driver. Adding
the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume
behaviour.
The rfkill state is maintained by the hardware over suspend/resume
so no extra consideration is needed here.

module_platform_driver()
This patch converts the drivers in drivers/platform/x86/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Add a software rfkill switch for the WLAN interface in the OLPC XO-1
laptop. It uses the OLPC embedded controller to cut/restore power to
the Marvell WLAN chip on the motherboard.
