Specified commit would break the pnp driver which is using
driver->shutdown.

Could you test this (untested) patch?

[PATCH] rtc_cmos: convert shutdown to new pnp_driver->shutdown

commit abd6633c67925f90775bb74755f9c547e30f1f20 adds shutdown method
to bus driver blindly. With it, driver->shutdown is invalid anymore.

Use pnp_driver->shutdown instead.
