5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Moshe Shemesh moshe@nvidia.com
[ Upstream commit b5d7b2f04ebcff740f44ef4d295b3401aeb029f4 ]
In case health counter has not increased for few polling intervals, miss counter will reach max misses threshold and health report will be triggered for FW health reporter. In case syndrome found on same health poll another health report will be triggered.
Avoid two health reports on same syndrome by marking this syndrome as already known.
