ASoC: ti: fix davinci_mcasp_probe dependencies

2019-05-31T13:43:58+00:00

[ Upstream commit 7d7b25d05ef1c5a1a9320190e1eeb55534847558 ]

The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as
a back-end, and it takes the presence of the respective dma engine
drivers in the configuration as an indication to which ones should be
built. However, this is flawed in multiple ways:

- With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y,
  is enabled as =m, and we get a link error:
  sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe':
  davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register'

- When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by
  another driver, the same link error appears even if CONFIG_TI_EDMA
  is disabled

There are possibly other issues here, but it seems that the only reasonable
solution is to always build both SND_SOC_TI_EDMA_PCM and
SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and
do not have any other compile-time dependencies, so the cost is
very small, and makes the configuration stage much more consistent.

ASoC: davinci-mcasp: Fix clang warning without CONFIG_PM

2019-05-31T13:43:57+00:00

[ Upstream commit 8ca5104715cfd14254ea5aecc390ae583b707607 ]

Building with clang shows a variable that is only used by the
suspend/resume functions but defined outside of their #ifdef block:

sound/soc/ti/davinci-mcasp.c:48:12: error: variable 'context_regs' is not needed and will not be emitted

We commonly fix these by marking the PM functions as __maybe_unused,
but here that would grow the davinci_mcasp structure, so instead
add another #ifdef here.

ASoC: wcd9335: fix a leaked reference by adding missing of_node_put

2019-05-31T13:43:43+00:00

[ Upstream commit 64b92de9603f22b5455da925ee57268ef7fb4e80 ]

The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

Detected by coccinelle with the following warnings:

ASoC: core: remove link components before cleaning up card resources

2019-05-31T13:43:37+00:00

[ Upstream commit f96fb7d198ca624fe33c4145a004eb5a3d0eddec ]

When the card is registered by the machine driver,
dai link components are probed after the snd_card is
created. This is done in snd_soc_bind_card() which calls
snd_soc_instantiate_card() to first create the snd_card
and then probes the link components by calling
soc_probe_link_components(). The snd_card is used by the
component driver to add the kcontrols associated
with dapm widgets to the card.

When the machine driver is unregistered, the snd_card
is freed when the card resources are cleaned up.
But the snd_card needs to be valid while unloading the
topology dapm widgets in order to remove the kcontrols
from the card.

Since, unloading topology is done when the component
driver is removed, the link components should be removed
in snd_soc_unbind_card(). This will ensure that the kcontrols
are removed before the card resources are cleaned up and
the snd_card itself is freed.

ASoC: fsl_sai: Update is_slave_mode with correct value

2019-05-31T13:43:23+00:00

[ Upstream commit ddb351145a967ee791a0fb0156852ec2fcb746ba ]

is_slave_mode defaults to false because sai structure
that contains it is kzalloc'ed.

Anyhow, if we decide to set the following configuration
SAI slave -> SAI master, is_slave_mode will remain set on true
although SAI being master it should be set to false.

Fix this by updating is_slave_mode for each call of
fsl_sai_set_dai_fmt.

ALSA: hda: fix unregister device twice on ASoC driver

2019-05-31T13:43:20+00:00

[ Upstream commit 4d95c51776b2edb4d4ebcea00b6e5a1fe538ce66 ]

snd_hda_codec_device_new() is used by both legacy HDA and ASoC
driver. However, we will call snd_hdac_device_unregister() in
snd_hdac_ext_bus_device_remove() for ASoC device. This patch uses
the type flag in hdac_device struct to determine is it a ASoC device
or legacy HDA device and call snd_hdac_device_unregister() in
snd_hda_codec_dev_free() only if it is a legacy HDA device.

ASoC: imx: fix fiq dependencies

2019-05-31T13:43:17+00:00

[ Upstream commit ea751227c813ab833609afecfeedaf0aa26f327e ]

During randconfig builds, I occasionally run into an invalid configuration
of the freescale FIQ sound support:

WARNING: unmet direct dependencies detected for SND_SOC_IMX_PCM_FIQ
  Depends on [m]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_IMX_SOC [=m]
  Selected by [y]:
  - SND_SOC_FSL_SPDIF [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_IMX_SOC [=m]!=n && (MXC_TZIC [=n] || MXC_AVIC [=y])

imx-ssi.c:(.text+0x28): undefined reference to `imx_pcm_fiq_exit'
sound/soc/fsl/imx-ssi.o: In function `imx_ssi_probe':
imx-ssi.c:(.text+0xa64): undefined reference to `imx_pcm_fiq_init'

The Kconfig warning is a result of the symbol being defined inside of
the "if SND_IMX_SOC" block, and is otherwise harmless. The link error
is more tricky and happens with SND_SOC_IMX_SSI=y, which may or may not
imply FIQ support. However, if SND_SOC_FSL_SSI is set to =m at the same
time, that selects SND_SOC_IMX_PCM_FIQ as a loadable module dependency,
which then causes a link failure from imx-ssi.

The solution here is to make SND_SOC_IMX_PCM_FIQ built-in whenever
one of its potential users is built-in.

ASoC: hdmi-codec: unlock the device on startup errors

2019-05-31T13:43:16+00:00

[ Upstream commit 30180e8436046344b12813dc954b2e01dfdcd22d ]

If the hdmi codec startup fails, it should clear the current_substream
pointer to free the device. This is properly done for the audio_startup()
callback but for snd_pcm_hw_constraint_eld().

Make sure the pointer cleared if an error is reported.
