From e485e5386d3df5f76ef2f81a09361309314da558 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:49:18 +0100 Subject: ALSA: maestro3: Use managed buffer allocation Clean up the driver with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped.
