by GitHub pull_request - opened 02 Jun '24

02 Jun '24

alsa-project/alsa-ucm-conf pull request #422 was opened from clement-dufour: Adds support for the [MOTU Ultralite mk5](https://motu.com/en-us/products/gen5/ultralite-mk5/) soundcard. I named each device after their names on the MOTU Cuemix Control application. Successfully tested on my hardware, see the [alsa-info.sh output](http://alsa-project.org/db/?f=ca07253279e53fa354820f356f6beb5d2026d….

[PATCH 0/7] ALSA: hda: Improvements to hda_component
by Simon Trimmer 01 Jun '24

01 Jun '24

This series of patches makes sure that the existing consumers of the infrastructure unbind their interface before they begin destroying the driver, moves duplicated members from the instanced component structures into a new parent structure and introduces locking so that consumers of the interface do not use stale data.

[PATCH] ALSA: hda: cs35l41: Possible null pointer dereference in cs35l41_hda_unbind()
by Simon Trimmer 31 May '24

31 May '24

The cs35l41_hda_unbind() function clears the hda_component entry matching it's index and then dereferences the codec pointer held in the first element of the hda_component array, this is an issue when the device index was 0. Instead use the codec pointer stashed in the cs35l41_hda structure as it will still be valid.
