Message-ID: <20070913233947.GD10856@kroah.com>
Date: Thu, 13 Sep 2007 16:39:47 -0700
From: Greg KH <greg@...ah.com>
To: linux-kernel@...r.kernel.org
Subject: Driver core: remove put_bus()
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.
Signed-off-by: Greg Kroah-Hartman <gregkh@...e.de>
