sound: don't call skl_init_chip() to reset intel skl soc

2018-10-18T07:16:22+00:00

[ Upstream commit 75383f8d39d4c0fb96083dd460b7b139fbdac492 ]

Internally, skl_init_chip() calls snd_hdac_bus_init_chip() which
1) sets bus->chip_init to prevent multiple entrances before device
is stopped; 2) enables interrupt.

We shouldn't use it for the purpose of resetting device only because
1) when we really want to initialize device, we won't be able to do
so; 2) we are ready to handle interrupt yet, and kernel crashes when
interrupt comes in.

Rename azx_reset() to snd_hdac_bus_reset_link(), and use it to reset
device properly.

sound: enable interrupt after dma buffer initialization

2018-10-18T07:16:22+00:00

[ Upstream commit b61749a89f826eb61fc59794d9e4697bd246eb61 ]

In snd_hdac_bus_init_chip(), we enable interrupt before
snd_hdac_bus_init_cmd_io() initializing dma buffers. If irq has
been acquired and irq handler uses the dma buffer, kernel may crash
when interrupt comes in.

Fix the problem by postponing enabling irq after dma buffer
initialization. And warn once on null dma buffer pointer during the
initialization.

ASoC: rsnd: don't fallback to PIO mode when -EPROBE_DEFER

2018-10-18T07:16:21+00:00

[ Upstream commit 6c92d5a2744e27619a8fcc9d74b91ee9f1cdebd1 ]

Current rsnd driver will fallback to PIO mode if it can't get DMA
handler. But, DMA might return -EPROBE_DEFER when probe timing.
This driver always fallback to PIO mode especially from
commit ac6bbf0cdf4206c ("iommu: Remove IOMMU_OF_DECLARE") because
of this reason.

The DMA driver will be probed later, but sound driver might be
probed as PIO mode in such case. This patch fixup this issue.
Then, -EPROBE_DEFER is not error. Thus, let's don't indicate error
message in such case.
And it needs to call rsnd_adg_remove() individually if probe failed,
because it registers clk which should be unregister.

Maybe PIO fallback feature itself is not needed,
but let's keep it so far.

ALSA: hda/realtek - Cannot adjust speaker's volume on Dell XPS 27 7760

commit 709ae62e8e6d9ac4df7dadb3b8ae432675c45ef9 upstream.

The issue is the same as commit dd9aa335c880 ("ALSA: hda/realtek - Can't
adjust speaker's volume on a Dell AIO"), the output requires to connect
to a node with Amp-out capability.

Applying the same fixup ALC298_FIXUP_SPK_VOLUME can fix the issue.
