From d577b6c8cf8ccaafda419a40af05c2eadac27bf7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:42 +0100 Subject: ALSA: ad1816a: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The hw_params and hw_free callbacks became superfluous and got dropped.
