Currently the presence of any optional TLVs in the wmi service available event leads to a parsing error with the below error message: ath10k_snoc 18800000.wifi: failed to parse svc_avail tlv: -71 The wmi service available event parsing should not return error for the newly added optional TLV. Fix this parsing for service available event message.
