Subject: app_adsiprog: Fix possible NULL dereference.
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3fe8e85617f3f640e6f7913bdd1ea8bf7378f0ec;p=thirdparty%2Fasterisk.git

app_adsiprog: Fix possible NULL dereference.

get_token can return NULL, but process_token uses this result without
checking for NULL; as elsewhere, check for a NULL result to avoid
possible NULL dereference.

Resolves: #1419
