Re: [RFC PATCH 1/3] ALSA: control: add kcontrol_type to control

Dne 08. 01. 21 v 12:23 Jaska Uimonen napsal(a):

Current kcontrol structs don't have a member to describe the control type. The type is present in the widget which contains the control. As there can be many controls in one widget it is inherently presumed that the control types are the same.

Lately there has been use cases where different types of controls would be needed for single widget. Thus enable this by adding the control type to kcontrol and kcontrol_new structs.

It looks like a SoC only extension. Use private_data to carry this information. It has no value for the toplevel code.
