Subject: [PATCH 4.9 02/43] ASoC: intel: atom: Fix reference to PCM buffer address
Date: Tue, 24 Aug 2021 13:05:33 -0400	[thread overview]
Message-ID: <20210824170614.710813-3-sashal@kernel.org> (raw)
In-Reply-To: <20210824170614.710813-1-sashal@kernel.org>

From: Takashi Iwai <tiwai@suse.de>

commit 2e6b836312a477d647a7920b56810a5a25f6c856 upstream.

PCM buffers might be allocated dynamically when the buffer
preallocation failed or a larger buffer is requested, and it's not
guaranteed that substream->dma_buffer points to the actually used
buffer.  The address should be retrieved from runtime->dma_addr,
instead of substream->dma_buffer (and shouldn't use virt_to_phys).

Also, remove the line overriding runtime->dma_area superfluously,
which was already set up at the PCM buffer allocation.
