From d635f09e919e6ea9214a7676e26ef6755b3453a0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 9 Dec 2019 10:48:39 +0100 Subject: [PATCH] ALSA: pcsp: 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() are dropped.
