2025-08-29ALSA: hda: Use auto cleanup macros for DSP loader locksTakashi Iwai
There are temporary DSP locking/unlocking patterns found in various places, and those can be cleaned up nicely with the guard() macro calling snd_hdac_dsp_lock() and *_unlock(). Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250827072916.31933-7-tiwai@suse.de
2025-08-29ALSA: hda/common: Use cleanup macros for PM controlsTakashi Iwai
The new macro CLASS(snd_hda_power_pm) can replace the manual snd_hda_power_up_pm() and _down() calls gracefully. A part of the code in codec_exec_verb() is factored out to a function, so that the auto-cleanup can be well scoped. Merely cleanups and no functional changes.

2025-08-29ALSA: hda: Introduce auto cleanup macros for PMTakashi Iwai
The temporary power up/down of the codec via snd_hda_power_up() and _down() (or snd_hda_power_up_pm() and _down_pm()) is seen in various places. This patch introduces simple auto-cleanup macros for those call patterns, so that the drivers don't have to call the corresponding power-down calls explicitly. Namely, err = snd_hda_power_up(codec); if (err < 0) return err; .... snd_power_down(codec); can drop the *_down() call by replacing with CLASS(snd_hda_power, pm)(codec); if (pm.err < 0) return pm.err; Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250827072916.31933-2-tiwai@suse.de

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v6.17 The main fixes here are for some of the cleanups done in the core in this release, we had broken component lookup in the case with a single bus and DMA controller. Otherwise it's driver specific changes, the shortlogs for the Intel WCL and rsnd drivers look like minor cleanups but are actually bugfixes (adding an op needed for correct functionality and reverting an inappropriate helper usage).

2025-08-29media: platform: mtk-mdp3: don't use %pK through printkThomas Weißschuh
In the past %pK was preferable to %p as it would not leak raw pointer values into the kernel log. Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping locks in atomic contexts. Switch to the regular pointer formatting which is safer and easier to reason about.

2025-08-29fhandle: use more consistent rules for decoding file handle from usernsAmir Goldstein
Commit 620c266f39493 ("fhandle: relax open_by_handle_at() permission checks") relaxed the coditions for decoding a file handle from non init userns. The conditions are that that decoded dentry is accessible from the user provided mountfd (or to fs root) and that all the ancestors along the path have a valid id mapping in the userns. These conditions are intentionally more strict than the condition that the decoded dentry should be "lookable" by path from the mountfd. For example, the path /home/amir/dir/subdir is lookable by path from unpriv userns of user amir, because /home perms is 755, but the owner of /home does not have a valid id mapping in unpriv userns of user amir. The current code did not check that the decoded dentry itself has a valid id mapping in the userns. There is no security risk in that, because that final open still performs the needed permission checks, but this is inconsistent with the checks performed on the ancestors, so the behavior can be a bit confusing. Add the check for the decoded dentry itself, so that the entire path, including the last component has a valid id mapping in the userns.

Replace the manual cpufreq_cpu_put() with __free(put_cpufreq_policy) annotation for policy references. This reduces the risk of reference counting mistakes and aligns the code with the latest kernel style. No functional change intended.
