[SVN commits to the DAHDI project]

Author: tzafrir
Date: Wed Dec  2 14:21:42 2009
New Revision: 7659

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=7659
Log:
Allow drivers to provide a proper location in the device tree

Add a new parent_device pointer. Should optionally be set before span
registration time.

If a span driver has already created a device node for the device that
holds the span, it should set the span_device pointer. If it is NULL, the
dummy dahdi_top one will be used.
