From 786e90b0d0f4ffc16237c05ac5cfc7285bf4e1bc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:34 +0100 Subject: [PATCH] ALSA: sparc: 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 dropped.
