[PATCH] [v2] ASoC: cs42l56: fix DT probe
by Arnd Bergmann 27 Jan '23

27 Jan '23

From: Arnd Bergmann <arnd(a)arndb.de> While looking through legacy platform data users, I noticed that the DT probing never uses data from the DT properties, as the platform_data structure gets overwritten directly after it is initialized. There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels or with the default values. For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.

[PATCH] ASoC: SOF: ipc4-topology: add buffer type support
by Peter Ujfalusi 26 Jan '23

26 Jan '23

From: Bard Liao <yung-chuan.liao(a)linux.intel.com> The corresponding IPC4 module of snd_soc_dapm_buffer widget is module -to-module copier. The module-to-module copier is a buffer-like component with demuxing capabilities. Rename the host_token_list to common_copier_token_list since it will be used by host copier and module-to-module copier. The setup callback is almost the same as sof_ipc4_widget_setup_pcm except the gtw_cfg data, and the free callback is exactly the same as sof_ipc4_widget_free_comp_pcm. To reduce the duplication, the commit reuses the setup and free callbacks.

[PATCH v2] ASoC: SOF: ipc4-topology: use different channel mask for each sdw amp feedback

From: Bard Liao <yung-chuan.liao(a)linux.intel.com> Currently, we use the same channel mask for aggregated speakers. It works fine for playback because we duplicate the audio data for all aggregated speakers. But we need to get audio data from each aggregated speaker and combine them to the captured audio.

This loop accidentally reuses the "i" iterator for both the inside and the outside loop. The value of MAX_STREAM_BUFFER is 5. I believe that chip->rmh.stat_len is in the 2-12 range. If the value of .stat_len is 4 or more then it will loop exactly one time, but if it's less then it is a forever loop.

[PATCH v2 0/6] introduce vm_flags modifier functions
by Suren Baghdasaryan 26 Jan '23

26 Jan '23

This patchset was originally published as a part of per-VMA locking [1] and was split after suggestion that it's viable on its own and to facilitate the review process. It is now a preprequisite for the next version of per-VMA lock patchset, which reuses vm_flags modifier functions to lock the VMA when vm_flags are being updated. VMA vm_flags modifications are usually done under exclusive mmap_lock protection because this attrubute affects other decisions like VMA merging or splitting and races should be prevented. Introduce vm_flags modifier functions to enforce correct locking. [1] https://lore.kernel.org/all/20230109205336.3665937-1-surenb@google.com/ The patchset applies cleanly over mm-unstable branch of mm tree. My apologies for an extremely large distribution list. The patch touches lots of files and many are in arch/ and drivers/.

[PATCH] ASoC: cs42l56: fix DT probe
by Arnd Bergmann 26 Jan '23

26 Jan '23

From: Arnd Bergmann <arnd(a)arndb.de> While looking through legacy platform data users, I noticed that this one could never be used with DT based probing as the platform_data structure gets overwritten directly after it is initialized. There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels. For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.
