2025-01-15platform/x86: alienware_wmi: General cleanup of WMAX methodsKurt Borja
Reorder variable declaration from longest to shortest. Standarize show/store method names of WMAX's sysfs groups.

2025-01-15platform/x86: alienware-wmi: Improve rgb-zones group creationKurt Borja
Define zone_attrs statically and initialize zone_attribute_group with platform driver's .dev_groups. Drop match_zone() and instead pass a `location` argument to previous show/store methods to access the correct `zone` LED state. On top of that rename zone_set() -> zone_store() to be more consistent with sysfs conventions.

2025-01-15hwmon: (drivetemp) Set scsi command timeout to 10sRussell Harmon
There's at least one drive (MaxDigitalData OOS14000G) such that if it receives a large amount of I/O while entering an idle power state will first exit idle before responding, including causing SMART temperature requests to be delayed. This causes the drivetemp request to exceed its timeout of 1 second.

2025-01-15ASoC: dapm: add support for preparing streamsMartin Blumenstingl
Codec driver can implement .hw_params and/or .prepare from struct snd_soc_dai_ops. For codec-to-codec links only the former (.hw_params) callback has been called. On platforms like Amlogic Meson8/8b/8m2 the SoC's sound card (sound/soc/meson/gx-card.c) uses a codec-to-codec link for the HDMI codec output because further digital routing is required after the backend. The new DRM HDMI (audio) codec framework (which internally uses sound/soc/codecs/hdmi-codec.c) relies on the .prepare callback of the hdmi-codec to be called. Implement calls to snd_soc_dai_prepare() so the .prepare callback is called. In this case the mandatory part is the call to prepare the sink (which is the hdmi-codec on those platforms). Also call snd_soc_dai_prepare() for the source to stay consistent with the rest of the code (even though it's not strictly necessary to make the DRM HDMI codec framework work on Amlogic Meson8/8b/8m2). For platforms or sound cards without a codec-to-codec link with additional parameters (which applies to most hardware) this changes nothing as the .prepare callback is already called via snd_pcm_do_prepare() (as well as dpcm_fe_dai_prepare() and dpcm_be_dai_prepare()) on those.

2025-01-15ASoC: simple-card-utils: fix priv->dai_props indexingLaurentiu Mihalcea
As of commit cb18cd26039f ("ASoC: soc-core: do rtd->id trick at snd_soc_add_pcm_runtime()") the ID stored in the PCM runtime data can no longer be safely used to index the priv->dai_props array. This is because the ID may be modified during snd_soc_add_pcm_runtime(), thus resulting in an ID that's no longer a valid array index. To fix this, use the position of the dai_link stored inside the PCM runtime data relative to the start of the dai_link array as index into the priv->dai_props array.

2025-01-15saner replacement for debugfs_rename()Al Viro
Existing primitive has several problems: 1) calling conventions are clumsy - it returns a dentry reference that is either identical to its second argument or is an ERR_PTR(-E...); in both cases no refcount changes happen. Inconvenient for users and bug-prone; it would be better to have it return 0 on success and -E... on failure. 2) it allows cross-directory moves; however, no such caller have ever materialized and considering the way debugfs is used, it's unlikely to happen in the future. What's more, any such caller would have fun issues to deal with wrt interplay with recursive removal. It also makes the calling conventions clumsier... 3) tautological rename fails; the callers have no race-free way to deal with that. 4) new name must have been formed by the caller; quite a few callers have it done by sprintf/kasprintf/etc., ending up with considerable boilerplate. Proposed replacement: int debugfs_change_name(dentry, fmt, ...). All callers convert to that easily, and it's simpler internally. IMO debugfs_rename() should go; if we ever get a real-world use case for cross-directory moves in debugfs, we can always look into the right way to handle that.

2025-01-15debugfs: don't mess with bits in ->d_fsdataAl Viro
The reason we need that crap is the dual use ->d_fsdata has there - it's both holding a debugfs_fsdata reference after the first debugfs_file_get() (actually, after the call of proxy ->open()) *and* it serves as a place to stash a reference to real file_operations from object creation to the first open. Oh, and it's triple use, actually - that stashed reference might be to debugfs_short_fops. Bugger that for a game of solidiers - just put the operations reference into debugfs-private augmentation of inode. And split debugfs_full_file_operations into full and short cases, so that debugfs_get_file() could tell one from another. Voila - ->d_fsdata holds NULL until the first (successful) debugfs_get_file() and a reference to struct debugfs_fsdata afterwards.

2025-01-15debugfs: get rid of dynamically allocation proxy_opsAl Viro
All it takes is having full_proxy_open() collect the information about available methods and store it in debugfs_fsdata. Wrappers are called only after full_proxy_open() has succeeded calling debugfs_get_file(), so they are guaranteed to have ->d_fsdata already pointing to debugfs_fsdata. As the result, they can check if method is absent and bugger off early, without any atomic operations, etc. - same effect as what we'd have from NULL method. Which makes the entire proxy_fops contents unconditional, making it completely pointless - we can just put those methods (unconditionally) into debugfs_full_proxy_file_operations and forget about dynamic allocation, replace_fops, etc. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Reviewed-by: Christian Brauner <brauner@kernel.org> Link: https://lore.kernel.org/r/20250112080705.141166-3-viro@zeniv.linux.org.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
