[PATCH 10/75] Driver core: remove put_bus()

[Greg Kroah-Hartman <gregkh@suse.de>]

put_bus() should not be globally visable as it is not used by anything
other than drivers/base/bus.c.  This patch removes the visability of it,
and renames it to match all of the other *_put() functions in the
kernel.
