New Revision: 184078

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=184078
Log:
Change NULL pointer check to be ast_strlen_zero.

The 'digit' variable is guaranteed to be non-NULL, so the if
statement could never evaluate true. Changing to ast_strlen_zero
makes the logic correct.

This was found while reviewing ast_channel_ao2 code review.
