To resolve this issue, have the platform driver core do this for the driver, making the individual drivers logic smaller and simpler, and solving the race at the same time. All of these patches depend on the first patch. I'll take the first one through my driver-core tree, and any subsystem maintainer can either ack their individul patch and I will be glad to also merge it, or they can wait until after 5.3-rc1 when the core patch hits Linus's tree and then take it, it's up to them. Thank to Richard Gong for the idea and the testing of the platform driver patch.
