Subject: [PATCH] rtlwifi: btcoex: 21a 2ant: init wlan when leave ips
Git-commit: 728b610677012b3eb047641c80b3ef515130a177
Patch-mainline: v4.13-rc1
References: FATE#326906
If the wifi is leaving ips, re-init the coex mechanisms, and before it is
going into ips, the bt can just ignore the wifi activities.
