ALSA: caiaq: Use managed buffer allocation
Clean up the driver with the new managed buffer allocation API. The hw_params callback became superfluous and dropped. The hw_free callback still remains because of the substream deactivation sync call. Link: https://lore.kernel.org/r/20191209094943.14984-66-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
