Subject: res_pjsip_pubsub: Increment persistence data ref when recreating.
X-Git-Tag: 17.3.0-rc1~35^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=35c9332edf013685cda733d275264877feb02707;p=thirdparty%2Fasterisk.git

res_pjsip_pubsub: Increment persistence data ref when recreating.

Each subscription needs to have a reference to the persisted data
for it, as well as the main JSON contained within the tree. When
recreating a subscription this did not occur and they both shared
the same reference.
