Subject: res_fax: Fix reference leak in fax_v21_session_new.
X-Git-Tag: 11.23.0-rc1~4^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4f0cc5ec5613a69744ec26f731e2f7b49435163;p=thirdparty%2Fasterisk.git

res_fax: Fix reference leak in fax_v21_session_new.

fax_v21_session_new created a session details object but only released
the allocation reference during error conditions.  fax_session_new adds
it's own reference to details if needed so the caller is always
responsible for cleaning it's own reference.
