2018-06-04ASoC: dapm: delete dapm_kcontrol_data paths list before freeing itSrinivas Kandagatla1-0/+2
dapm_kcontrol_data is freed as part of dapm_kcontrol_free(), leaving the paths pointer dangling in the list. This leads to system crash when we try to unload and reload sound card. I hit this bug during ADSP crash/reboot test case on Dragon board DB410c.

2018-06-01ASoC: topology: Improve backwards compatibility with v4 topology filesGuenter Roeck3-2/+248
Commit dc31e741db49 ("ASoC: topology: ABI - Add the types for BE DAI") introduced sound topology files version 5. Initially, this change made the topology code incompatible with v4 topology files. Backwards compatibility with v4 configuration files was subsequently added with commit 288b8da7e992 ("ASoC: topology: Support topology file of ABI v4"). Unfortunately, backwards compatibility was never fully implemented. First, the manifest size in (Skylake) v4 configuration files is set to 0, which causes manifest_new_ver() to bail out with error messages similar to the following. snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size snd_soc_skl 0000:00:1f.3: tplg component load failed-22 snd_soc_skl 0000:00:1f.3: Failed to init topology! snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22 skl_n88l25_m98357a skl_n88l25_m98357a: ASoC: failed to instantiate card -22 skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22 After this problem is fixed, the following error message is seen instead. snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482 snd_soc_skl 0000:00:1f.3: ASoC: failed to load widget media0_in cpr 0 snd_soc_skl 0000:00:1f.3: tPlg component load failed-22 This message is seen because backwards compatibility for loading widgets was never implemented. The lack of audio support when running the upstream kernel on recent Chromebooks has been reported in various forums, and can be traced back to this problem. Attempts to fix the problem, usually by providing v5 configuration files, were only partially successful. Let's implement backward compatibility properly to solve the problem for good.

2018-06-01ASoC: Intel: kbl: Move codec sysclk config to codec_init functionMac Chiang1-8/+9
On APL, commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function") fixed an issue related to jack detection. The MCLK for DA7219 does not change in this platform, but is currently being configured everytime as part of the platform_clock event handler for DAPM. The upshot of this is that we have unnecessary calls to this function, and it also means that if a stream hasn't yet been started, DA7219 driver does not have the correct MCLK rates programmed and so the HP detection feature does not operate as expected. The same fix is needed on KBL. This patch rectifies this issue by moving the sysclk call to codec_init function so it's only called once at initialisation.

2018-06-01ASoC: simple-card: set cpu dai clk in hw_paramsDaniel Mack1-0/+21
The simple-card driver currently accepts a clock node in the cpu dai sub-node and only uses it as an alternative to the 'system-clock-frequency' property to get the current frequency. This patch adds another use of the passed clock node. If mclk-fs is specified, the clocks in cpu and codec dai sub-nodes will be set to the calculated rate (stream rate * mclk_fs) in hw_params. This allows platforms to pass tuneable clocks as phandle that will automatically be set to the right rates.

2018-06-01ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream()Bo Chen1-1/+3
When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is created without setting its operators via 'snd_pcm_set_ops()'. Following operations on the new pcm instance can trigger kernel null pointer dereferences and cause kernel oops. This bug was found with my work on building a gray-box fault-injection tool for linux-kernel-module binaries. A kernel null pointer dereference was confirmed from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in file 'sound/core/pcm_native.c'. This patch fixes the bug by calling 'snd_device_free()' in the error handling path of 'kzalloc()', which removes the new pcm instance from the snd card before returns with an error code.

2018-05-31ASoC: Intel: bytcr_rt5651: Set card long_name based on quirksHans de Goede1-0/+11
Many X86 devices using a BYT SoC + RT5651 codec are cheap devices with generic DMI strings, causing snd_soc_set_dmi_name() to fail to set a long_name, making it impossible for userspace to have a correct UCM profile which knowns which input is connected to the internal mic, which input is connected to the hsmic (for correct jack-based switching) and which inputs are unused. Our quirks already specify which inputs the internal and headset mic are connected to. This commit sets a long_name based on the quirks so that userspace can have UCM profiles doing the right thing based on the long_name. Note that if we ever encounter the need for a special UCM profile for some device we can add a quirk to set a specific long_name for the device, Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2018-05-29ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffersTakashi Iwai5-5/+63
Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as this serves merely as an intermediate buffer that is copied to each URB transfer buffer. This works well in general on x86, but on some archs this may result in cache coherency issues when mmap is used. OTOH, it works also on such arch unless mmap is used. This patch is a step for mitigating the inconvenience; a new module option "use_vmalloc" is provided so that user can choose to allocate the DMA coherent buffer instead of the existing vmalloc buffer. The drawback is that it'd be the standard dma_alloc_coherent() calls and the system would require contiguous pages on non-x86 archs. Note that it's a global option and not dynamically switchable since the buffer is pre-allocated at the probe time. In theory, it's possible to be switchable, but it'd be trickier and racier. As default use_vmalloc option is set to true, so that the old behavior is kept. For allowing the coherent mmap on ARM or MIPS, pass use_vmalloc=0 option explicitly.

2018-05-28ALSA: xen-front: remove redundant error check on retColin Ian King1-2/+0
The error for a -ve value in ret is redundant as all previous assignments to ret have an associated -ve check and hence it is impossible for ret to be less that zero at the point of the check. Remove this redundant error check.

2018-05-27ALSA: dice: unuse second stream for MIDI conformant data channel for TC ↵Takashi Sakamoto1-5/+3
Electronic models At present, all of models produced by TC Electronic except for Konnekt Live are supported with hard-coded their stream formats. Studio Konnekt 48 is sore model to support dual streams for both directions. The second stream has no MIDI conformant data channel in its data block. But current implementation transfers the second stream with MIDI conformant data channel. This commit fixes this issue.
