[alsa-devel] [PATCH v2 0/4] Add NXP AUDMIX device and machine drivers
by Viorel Suman 16 Jan '19

16 Jan '19

The patchset adds NXP Audio Mixer (AUDMIX) device and machine drivers and related DT bindings documentation. Changes since V1: 1. Original patch split into distinct patches for the device driver and DT binding documentation. 2. Replaced AMIX with AUDMIX in both code and file names as it looks more RM-compliant. 3. Removed polarity control from CPU DAI driver as suggested by Nicolin. 4. Added machine driver and related DT binding documentation.

[alsa-devel] [PATCH] ASoC: core: Don't defer probe on optional, NULL components
by Matthias Reichl 15 Jan '19

15 Jan '19

cpu and platform are optional components in DAI links. For example codec-codec links usually have no platform set. Call snd_soc_find_component only if the name or of_node of a cpu or platform is set. Otherwise it will return NULL and soc_init_dai_link bails out immediately with -EPROBE_DEFER, meaning registering a card with NULL cpu or platform in DAI links can never succeed.

[alsa-devel] Applied "ASoC: dapm: change snprintf to scnprintf for possible overflow" to the asoc tree
by Mark Brown 15 Jan '19

15 Jan '19

The patch ASoC: dapm: change snprintf to scnprintf for possible overflow has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[alsa-devel] [PATCH] ASoC: amd: Fix potential NULL pointer dereference
by Gustavo A. R. Silva 15 Jan '19

Check return value from call to devm_kzalloc() in order to prevent a potential NULL pointer dereference. Also, notice that it makes no sense to allocate any resources if res = platform_get_resource(pdev, IORESOURCE_MEM, 0); fails, so move the call to devm_kzalloc() below the mentioned code. Lastly, improve the use of sizeof in the call to devm_kzalloc() by changing it from sizeof(struct i2s_dev_data) to sizeof(*adata) This issue was detected with the help of Coccinelle.
