Subject: [alsa-devel] [PATCH 15/24] ALSA: vx: Convert to the common vmalloc memalloc
Date: Tue,  5 Nov 2019 16:18:47 +0100
Message-ID: <20191105151856.10785-16-tiwai@suse.de> (raw)
In-Reply-To: <20191105151856.10785-1-tiwai@suse.de>

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.
(*) df3fd6509421: ALSA: memalloc: Add vmalloc buffer allocation
                  support
    6ef6be988f98: 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().
