[PATCH 1/5] soundwire: sysfs: move sdw_slave_dev_attr_group into the existing list of groups
by Greg Kroah-Hartman 24 Aug '22

24 Aug '22

The sysfs logic already creates a list of groups for the device, so add the sdw_slave_dev_attr_group group to that list instead of having to do a two-step process of adding a group list and then an individual group. This is a step on the way to moving all of the sysfs attribute handling into the default driver core attribute group logic so that the soundwire core does not have to do any of it manually.

[PATCH 1/2] ALSA: seq: oss: Fix data-race for max_midi_devs access
by Takashi Iwai 24 Aug '22

24 Aug '22

ALSA OSS sequencer refers to a global variable max_midi_devs at creating a new port, storing it to its own field. Meanwhile this variable may be changed by other sequencer events at snd_seq_oss_midi_check_exit_port() in parallel, which may cause a data race. OTOH, this data race itself is almost harmless, as the access to the MIDI device is done via get_mdev() and it's protected with a refcount, hence its presence is guaranteed. Though, it's sill better to address the data-race from the code sanity POV, and this patch adds the proper spinlock for the protection.

[PATCH 0/4] ASoC: SOF: Intel: override mclk_id for ES8336 support
by Pierre-Louis Bossart 24 Aug '22

24 Aug '22

This patchset solves a known issue with ES8336 platforms wrt MCLK selection. Most of the devices use the MCLK0 signal, but some devices do use the MCLK1 signal. The MCLK is defined in the topology, it would be a nightmare to generate more topology files just for one MCLK difference. With a minor extension to the intel-nhlt library, the MCLK information can be found by parsing the NHLT table, and we can override the mclk_id at boot time. The only known issues for this platform remain the detection of GPIO and microphone connections, currently only possible with manual quirks. Thanks to Eugene J. Markow for testing this patchset.
