From ee88f4ebe57523889fc437bc42f95d9ab89bdd9f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:49 +0100 Subject: ALSA: mips: Use managed buffer allocation Clean up the drivers with the new managed buffer allocation API. The hw_params and hw_free callbacks became superfluous and got dropped.
