driver-core: Move kobj_to_dev from genhd.h to device.h
This function is not really specific to the genhd layer and there are various re-implementations or open-coded variants of it all throughout the kernel. To avoid further duplications move the function to a more generic place. While moving also convert it from a macro to a inline function. Potential users of this function can be detected and converted using the following coccinelle patch: // <smpl> @@ expression k; @@ -container_of(k, struct device, kobj) +kobj_to_dev(kobj) // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
