From 01001fa1c79e2bb6698c289010352cae7b0a142d Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:30 +0100 Subject: [PATCH] ALSA: pmac: 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.
