[SVN commits to the Digium repositories]

Author: sruffell

New Revision: 9341

URL: http://svnview.digium.com/svn/dahdi?view=rev&rev=9341
Log:
dahdi: Save pointer to monitored channel in struct dahdi_chan.

When we're in monitor mode, we can save a pointer to the channel we are
monitoring directly instead of dereferencing the 'chans' array each
time.
