It's still useful to share as much of the code as possible to ensure consistency between devices. Most devices are able to use the generic register cache formatting (which is all that uses the size and step) as is and as a general rule it makes maintinence easier when code is factored out of individual drivers. > It's the sprintf that is the problem.

I'd suggest adding an optional callback that drivers can use to replace the register value display (just the value) so that existing drivers don't need modification to cope with larger register sizes - it's not the common case, after all. If there are devices that use these larger registers for operations that are handled by snd_soc_update_bits() and friends that'd require more but I'd be surprised to see such devices. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
