ALSA: hda: Add controller matching macros

2023-07-18T12:22:17+00:00

Some HDA controllers require additional handling, so there are macros to match them, however those are spread across multiple files. Add them all in one place, so they can be reused.

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...

ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer

2022-10-20T12:31:42+00:00

The SPIB and DRMS capabilities are orthogonal to the DSP enablement and can be used whether the stream is coupled or not. The existing code partitioning makes limited sense, the capabilities are parsed at the sound/hda level but helpers are located in sound/hda/ext. This patch moves all the SPIB/DRMS functionality to the sound/hda layer. This reduces the complexity of the sound/hda/ext layer which is now limited to handling the multi-link extensions and stream coupling/decoupling helpers. Note that this is an iso-functionality code move and rename, the HDaudio legacy driver would need additional changes to make use of these capabilities.

ALSA: hda: Update register polling macros

Recent commit d91857059def ("ALSA: hda: Rework snd_hdac_stream_reset() to use macros") missed that on some devices register access needs to be done with unaligned access helper. Change polling macros to use read_poll_timeout_atomic() in order to specify register read function.

ALSA: hda: ext: fix locking in stream_release

2022-09-20T06:08:14+00:00

The snd_hdac_ext_stream_release() routine uses the bus reg_lock, but releases it before calling snd_hdac_stream_release() where the bus reg_lock is taken again. This creates a timing window where the link stream release could test an invalid 'opened' boolean status and fail to recouple the host and link parts. Fix by exposing a locked version of snd_hdac_stream_release() and use it without releasing the spinlock.
