-Subject: [PATCH] ath10k: wmi: modify svc bitmap parsing for wcn3990
-
-Due to the limitation of wmi tlv parsing logic, if there are
-two parameters in a wmi event with same tlv tag, we can get only
-the last value, as it overwrites the prev value of the same tlv tag.
-
-The service ready event in wcn3990 contains two parameters of the
-same tag UINT32, due to which the svc bitmap is overwritten with the
-DBS support parameter.
-
-Refactor the service ready event parsing to allow parsing two tlv
-of the same tag UINT32 for wcn3990.
