2026-02-03ALSA: aloop: Fix racy access at PCM triggerTakashi Iwai
The PCM trigger callback of aloop driver tries to check the PCM state and stop the stream of the tied substream in the corresponding cable. Since both check and stop operations are performed outside the cable lock, this may result in UAF when a program attempts to trigger frequently while opening/closing the tied stream, as spotted by fuzzers. For addressing the UAF, this patch changes two things: - It covers the most of code in loopback_check_format() with cable->lock spinlock, and add the proper NULL checks. This avoids already some racy accesses. - In addition, now we try to check the state of the capture PCM stream that may be stopped in this function, which was the major pain point leading to UAF.

2025-12-14ALSA: opl3: Convert to snd_seq bus probe mechanismUwe Kleine-König
The snd_seq bus got a dedicated probe function. Make use of that. This fixes a runtime warning about the driver needing to be converted to the bus probe method. Note that the remove callback returns void now. The actual return value was ignored before (see device_remove() in drivers/base/dd.c), so there is no problem introduced by converting `return -EINVAL` to `return`.

2025-11-19ALSA: pcmtest: Replace deprecated strcpy with strscpy_pad in setup_patt_bufsThorsten Blum
strcpy() has been deprecated [1] because it performs no bounds checking on the destination buffer, which can lead to buffer overflows. Replace it with the safer strscpy_pad(), and use kmalloc() instead of kzalloc() because strscpy_pad() zero-pads the destination buffer and therefore avoids writing to it twice.

2024-10-30sound: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below sound to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.
