Subject: [PATCH 1/2] ASoC: wm_adsp: Add control_add callback and export wm_adsp_control_add()
The callback allows codec drivers to affect how firmware coefficients
are added as controls.
For example a codec driver may selectively add controls by choosing to
call wm_adsp_control_add() based on some filter logic.
