From d5dec270c00c155db64c3d2151b94002dfb2c6c7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 5 Nov 2019 16:18:48 +0100 Subject: [PATCH] ALSA: pdaudiocf: Convert to the common vmalloc memalloc The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code. (*) 1fe7f397cfe2: ALSA: memalloc: Add vmalloc buffer allocation support 7e8edae39fd1: ALSA: pcm: Handle special page mapping in the default mmap handler Since the driver requires the DMA32 allocation, it passes the specially encoded device to snd_pcm_lib_preallocate_pages().
