Hi!
Changelog explains author is not sure if this will break existing setups:
This rate change wasn't propagated until now, and it's unclear about cases where this shouldn't be propagated. Thus, it's unclear whether this is fixing a bug, or extending the current driver behavior. Also, it's unsure about whether this may break any existing setups; in the case that it does, a device-tree property may be added to disable this flag.
I don't see explanation how this fixes any user bug, so this may not be good patch for stable?
Best regards, Pavel
