From ff3eb3d51be9d191fe3e663d0e95ed8b28824a89 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:24 +0100 Subject: [PATCH] ALSA: sis7019: 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.
