Subject: [PATCH] rtlwifi: btcoex: 21a 1ant: re-init coex after wifi leaves IPS
Git-commit: ee406cec878941d997d4e7e02493079cf21109ec
Patch-mainline: v4.13-rc1
References: FATE#326906
Before entering IPS, set the PTA control to default value and re-init it
after it leaves IPS to avoid running some redundant code in
run_coexist_mechanism.
