From 07ed72ba4d45601313848664e97cb2fc5d71f45d Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:46 +0100 Subject: ALSA: sb: 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.
