ALSA: control: code refactoring for TLV request handler to user element set User-defined element set registers own handler to get callbacks from TLV ioctl handler. In the handler, execution path bifurcates depending on requests from user space. At write request, container in given buffer is registered to the element set, or replaced old TLV data. At the read request, the registered data is copied to user space. The command request is not allowed. In current implementation, function of the handler includes codes for the two cases. This commit adds two helper functions for these cases so that readers can easily get the above design.
