Thanks, Broonie. New question from one of my customers.
Right, the combination within the driver rather than combining things at the subsystem level is causing you trouble here. It's sufficiently non standard that you probably do need to open code something here, but the broad point that we shouldn't have this unrestricted write feature available in production kernels remains - something similar to what regmap is doing for example.
May I create a debugfs node in the driver for "Acoustic tuning"?
Sure, something in debugfs is fine - it's just the unrestricted writes in production thing that was a concern.
