From fc97aef32338c5d5d9454f49655a275af03b2911 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:01 +0100 Subject: [PATCH] ALSA: ca0106: 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.
