Is this behavior achieved really by these patches? As far as I read
these two patches, they change how values are stored in the rb-tree.
Now it'll be partially an array instead of one-value-per-node. But,
this doesn't change how snd_soc_read() / snd_soc_write() are called.
Could you give an example which driver would be influenced actually?
