From 403d026c43763241e0d44086cdce3df4706c9454 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:32 +0100 Subject: ALSA: aica: 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.
