From fa84cf094ef9667e2b91c104b0a788fd1896f482 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 18 Jul 2018 07:40:53 +0200 Subject: [PATCH] ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc() snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with somewhat special for vmalloc handling, but in the end, this turned to just the default handler, i.e. NULL. As the situation has never changed over decades, let's rip it off.
