From 7641d549b13bbb1dcc6c7759c010c1ca288c90be Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:41 +0100 Subject: [PATCH] ALSA: firewire: Use managed buffer allocation Clean up the drivers with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped.
