[PATCH v2] ASoC: sh: rz-ssi: Improve error handling in rz_ssi_probe() error path
by Biju Das 05 Aug '22

05 Aug '22

We usually do cleanup in reverse order of init. Currently in case of error rz_ssi_release_dma_channels() done in the reverse order. This patch improves error handling in rz_ssi_probe() error path. While at it, use "goto cleanup" style to reduce code duplication.

[PATCH] ASoC: fsl_sai: fix incorrect mclk number in error message
by Pieterjan Camerlynck 05 Aug '22

In commit <c3ecef21c3f26> ("ASoC: fsl_sai: add sai master mode support") the loop was changed to start iterating from 1 instead of 0.

[PATCH] ASoC: fsl_asrc_dma: fully initialize structs
by Sascha Hauer 05 Aug '22

05 Aug '22

The driver uses two statically ininitialized struct dma_slave_config, but only one of them is initialized to zero. Initialize config_be to zero as well to make sure that no fields are filled with random values. Let the compiler do this instead of explicitly calling memset() which makes it easier to read.

[PATCH v3] ASoC: dt-bindings: fsl,sai: Convert format to json-schema
by Shengjiu Wang 02 Aug '22

Convert the NXP SAI binding to DT schema format using json-schema. The Synchronous Audio Interface (SAI) provides an interface that supports full-duplex serial interfaces with frame synchronization formats such as I2S, AC97, TDM, and codec/DSP interfaces. Beside conversion, 'fsl,shared-interrupt' and '#sound-dai-cells' are added for they are already used by some dts.

[PATCH v2 0/4] ALSA: Defer async signal handling
by Takashi Iwai 01 Aug '22

01 Aug '22

Hi, this is a revised patch series for another attempt to address the potential deadlocks via kill_fasync() calls that have been reported by syzbot for long time. Only a missing linux/fs.h inclusion was added from v1 series[1]. Instead of the previous series to drop the async handler[2], this tries to defer the kill_fasync() call. A few new common helpers are introduced at first, then the actual usages are replaced in the following patches. The patches passed the quick tests with alsa-lib test cases.
