ASoC: rsnd: ssi: 24bit data needs right-aligned settings

2017-08-30T08:19:28+00:00

commit f46a93b820eb3707faf238cd769a004e2504515f upstream.

Data left/right aligned is controlled by PDTA bit on SSICR.
But default is left-aligned. Thus 24bit sound will be very small sound
without this patch.

ASoC: rsnd: Add missing initialization of ADG req_rate

2017-08-30T08:19:28+00:00

commit 8b27418f300cafbdbbb8cfa9c29d398ed34d6723 upstream.

If the "clock-frequency" DT property is not found, req_rate is used
uninitialized, and the "audio_clkout" clock will be created with an
arbitrary clock rate.

This uninitialized kernel stack data may leak to userspace through
/sys/kernel/debug/clk/clk_summary, cfr. the value in the "rate" column:

       clock     enable_cnt  prepare_cnt        rate   accuracy   phase
    --------------------------------------------------------------------
     audio_clkout         0            0  4001836240          0 0

ASoC: rsnd: avoid pointless loop in rsnd_mod_interrupt()

2017-08-30T08:19:28+00:00

commit 2daf71ad8da6cb57f919c9c876ee7e42530371df upstream.

Current Renesas sound driver doesn't have 1:1 relationship between
stream <-> mod because it is supporting MIX. Because of this reason
rsnd_mod_interrupt() is searching correspond mod by for loop.
But this loop is not needed, because each mod has own type.
This patch avoid pointless loop by using mod->type.

This patch is good for SSI-parent support, because stream might have
2 SSI as SSI-parent/child. SSI interrupt handler will be called twice
if stream has SSI-parent without this patch.

ASoC: rsnd: disable SRC.out only when stop timing

2017-08-30T08:19:27+00:00

commit b761bf272bce6dff4d8a7ccf4385c9f3d4018094 upstream.

Because SRC is connected to DMA and DMA want to keep dreq when stop
timing. This patch makes SRC stop SRC.out only when stop timing. And
it stops both SRC.out/SRC.in when quit timing

ASoC: simple-card: don't fail if sysclk setting is not supported

2017-08-30T08:19:27+00:00

commit ee43a1a0cd2a8f33cddfa1323a60b5cfcf865ba0 upstream.

Commit e22579713ae1 ("ASoC: simple card: set cpu-dai sysclk
with mclk-fs") added sysclk / SND_SOC_CLOCK_OUT setting, that makes
asoc_simple_card_hw_params fail if the operation is not supported,
although the intention clearly was to ignore ENOTSUPP. Fix it.

The patch fixes audio playback on Kirkwood / OpenRD client,
where the following errors are seen:

	asoc-simple-card sound: ASoC: machine hw_params failed: -524
	alsa-lib: /alsa-lib-1.0.28/src/pcm/pcm_hw.c:327:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed (-524): Unknown error 524

ALSA: hda - Add stereo mic quirk for Lenovo G50-70 (17aa:3978)

2017-08-30T08:19:22+00:00

commit bbba6f9d3da357bbabc6fda81e99ff5584500e76 upstream.

Lenovo G50-70 (17aa:3978) with Conexant codec chip requires the
similar workaround for the inverted stereo dmic like other Lenovo
models.

ALSA: core: Fix unexpected error at replacing user TLV

2017-08-30T08:19:22+00:00

commit 88c54cdf61f508ebcf8da2d819f5dfc03e954d1d upstream.

When user tries to replace the user-defined control TLV, the kernel
checks the change of its content via memcmp().  The problem is that
the kernel passes the return value from memcmp() as is.  memcmp()
gives a non-zero negative value depending on the comparison result,
and this shall be recognized as an error code.

The patch covers that corner-case, return 1 properly for the changed
TLV.

ALSA: usb-audio: Add mute TLV for playback volumes on C-Media devices

2017-08-25T00:02:35+00:00

commit 0f174b3525a43bd51f9397394763925e0ebe7bc7 upstream.

C-Media devices (at least some models) mute the playback stream when
volumes are set to the minimum value.  But this isn't informed via TLV
and the user-space, typically PulseAudio, gets confused as if it's
still played in a low volume.

This patch adds the new flag, min_mute, to struct usb_mixer_elem_info
for indicating that the mixer element is with the minimum-mute volume.
This flag is set for known C-Media devices in
snd_usb_mixer_fu_apply_quirk() in turn.

ALSA: usb-audio: Apply sample rate quirk to Sennheiser headset

2017-08-25T00:02:35+00:00

commit a8e800fe0f68bc28ce309914f47e432742b865ed upstream.

A Senheisser headset requires the typical sample-rate quirk for
avoiding spurious errors from inquiring the current sample rate like:
 usb 1-1: 2:1: cannot get freq at ep 0x4
 usb 1-1: 3:1: cannot get freq at ep 0x83

The USB ID 1395:740a has to be added to the entries in
snd_usb_get_sample_rate_quirk().
