[asterisk-commits] mmichelson: branch 12 r402767 - /branches/12/main/channel.c

[SVN commits to the Asterisk project]

Author: mmichelson

New Revision: 402767

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=402767
Log:
Move a NULL check to a place that makes more sense.

Two variables were being checked for NULLity immediately
after being declared NULL. I moved the NULL check until
after the variables are allocated.

This allows for the "channelvars" option in manager.conf
to work as intended again.
