treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00+00:00

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

ALSA: wavefront: Use auto-cleanup for firmware loading

2026-07-31T10:44:36+00:00

Simplify the code to manage the firmware loading with __free(firmware) auto-cleanup. Only the code refactoring, no functional changes. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260729083735.120219-9-tiwai@suse.de

ALSA: Improve style of pnp_device_id array terminators

2026-06-10T07:25:03+00:00

To match how device-id array terminators look like for other device types drop `.id = ""` from it and let the compiler care for zeroing the entry. There are no changes in the compiled drivers, only the source looks nicer.

ALSA: es18xx: check control allocation before private data setup

2026-06-07T09:45:03+00:00

snd_es18xx_mixer() creates controls with snd_ctl_new1() and then stores bookkeeping pointers or sets private_free before calling snd_ctl_add(). snd_ctl_new1() can return NULL on allocation failure, so those writes can dereference a NULL control pointer. Check the returned control pointers before using them and return -ENOMEM on allocation failure.

ALSA: gus: check snd_ctl_new1() return value

2026-05-28T07:35:21+00:00

snd_ctl_new1() can return NULL when memory allocation fails. snd_gf1_pcm_volume_control() does not check the return value before dereferencing kctl->id.index, which can lead to a NULL pointer dereference. Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.

2026-05-25T07:31:31+00:00

The '*_registered' variables are initialized only during the init phase in the '__init' functions and never changed. So, mark them as __ro_after_init to reduce the attack surface.

ALSA: wavefront: add suspend and resume support

2026-04-29T05:52:22+00:00

The WaveFront driver still lacks support for suspend and resume in both the ISA and PnP driver tables. Wire the driver into ALSA PM by storing the WSS codec pointer in the card private data and adding shared suspend/resume callbacks. Resume cannot simply rerun snd_wavefront_start(), because with the default fx_raw=1 setting that would reset the synth on every resume and discard uploaded WaveFront RAM contents. Cache wavefront.os for PM, probe the ICS2115 after resume and only run the full reset/bootstrap path when the board comes back raw. When the firmware is still running, refresh the software slot bookkeeping and restore the MIDI routing state without forcing a synth reset. Also quiesce and restart the WaveFront MIDI output timer across suspend and resume so active rawmidi output does not race the PM transition. This restores the card to a usable baseline after resume while preserving uploaded samples and programs when the hardware state survives suspend. If the board resumes raw, userspace still needs to reload custom synth contents.

ALSA: opti9xx: restore snd-miro state after resume

2026-04-27T11:44:27+00:00

snd-miro has no PM callbacks, so system resume leaves the OPTi master-control registers and the board-specific ACI mixer state unrestored. Like snd-opti9xx, the driver needs to reprogram the OPTi routing registers before bringing the codec back. snd-miro also keeps mixer state in the ACI block, so the codec resume callback alone is not enough here. Save the ACI mixer state on suspend, reinitialize the OPTi and ACI state on resume, replay the saved ACI values, and then resume the WSS codec. Hook the PM handlers into both the ISA and PnP paths. Also initialize miro->card on the ISA path for the existing dev_*() logging and keep the cached solo-mode value aligned with the value written to hardware. PCM20 radio tuner state remains outside this driver's PM scope.
