X-Git-Tag: 12.7.0-rc1~53
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb88076a3554dc8622f476309441a3801af0a5d6;p=thirdparty%2Fasterisk.git

res_fax: Resolve module reference leak caused by reserved sessions

Remove reference to module providing reserved session after
adding a reference to the final module.  This re-reference
is done to ensure that module references are correct even
if the final session selects a different module than the
reserved session.
