platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
This patch fixes the bug reported in http://bugzilla.kernel.org/show_bug.cgi?id=11681. "Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <email@example.com> Acked-by: Henrique de Moraes Holschuh <firstname.lastname@example.org> Acked-by: David Brownell <email@example.com> Signed-off-by: Greg Kroah-Hartman <firstname.lastname@example.org>
