[svn-commits] sruffell: linux/trunk r9130 - in /linux/trunk/include/dahdi: kernel.h user.h

New Revision: 9130

Log:
dahdi: Make it clear that 'linecompat' can be used to identify analog spans.

The linecompat member can be used by a span to identify the
global-to-the-span signalling types supported. Analog spans do not
support any span-global signalling and therefore linecompat should
always be 0.
