That would need fixed first before this change can be made. Thanks, Charles

The rest don't do that and I just double checked that they compile cleanly. Those two cases where modifications are required rely on values that are not known until they are probed. I think it makes then sense that they are left as they are, so I will drop both drivers for v2. Best regards, Javier Carrasco

The instances of the `snd_soc_component_driver` struct are not modified after their declaration, and they are only passed to `devm_snd_soc_register_component()`, which expects a constant `snd_soc_component_driver`. Move all instances of `snd_soc_component_driver` to read-only sections by declaring them const.
