[SVN commits to the Asterisk project]

Author: rmudgett

New Revision: 367906

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=367906
Log:
Coverity Report: Fix issues for error type REVERSE_INULL (deprecated modules)

* Fix only issue pointed out by deprecated_REVERSE_INULL.txt for
app_meetme.c in find_user().

* Change use of %i to %d in sscanf() in find_user().  The use of %i gives
unexpected parsing because it can accept hex, octal, and decimal integer
formats.

* Changed other uses of %i in app_meetme() to use %d for consistency.
