These are the only freqs that appear as duplicates and will be fixed with a firmware update. FWIW the warnings that we are addressing in this series will also get fixed by a firmware update but they still have to land for devices already out in the wild. V3: * Pick up R-b, T-b from the list. * Pick up the updated patch from Cristian for skipping opps. * Update device names only when a name collision occurs [Dmitry/Ulf] * Drop Johan's T-b from "fix debugfs node creation failure" * Move scmi_protocol_msg_check to the top [Sudeep] V2: * Include the fix for do_xfer timeout * Include the fix debugfs node creation failure * Include Cristian's fix for skipping opp duplication V1: * add missing MSG_SUPPORTS_FASTCHANNEL definition.
