Commit log seems a bit lacking. You could probably explain how you found this, either when comparing datasheet macros, or some actual error manifested and you "heard" it. You could also state what the fixed outcome should be.
Also please add a fixes tag.
The RX channel select offset should be added as a separate patch, also with an explanation on how you found this missing, and a fixes tag.
