From 247ed1020476bfdec52459f4019c75d596e27156 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:11 +0100 Subject: [PATCH] ALSA: fm801: 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.
