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

Greg Kroah-Hartman
2007-10-12T22:23:15Z

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.
