2026-04-10HID: logitech-dj: fix wrong detection of bad DJ_SHORT output reportBenjamin Tissoires
commit b6a57912854e ("HID: logitech-dj: Prevent REPORT_ID_DJ_SHORT related user initiated OOB write") assumed that all HID devices attached to the logitech-dj driver was having an output report of DJ_SHORT. However, on the receiver itself, we have 2 other HID device we attach here: the mouse emulation and the keyboard emulation. For those devices the value of rep is NULL and we are triggered a segfault here. This is doubly required because logitech-dj also handles non DJ devices that might not have the DJ collection.

2026-04-10ALSA: usb-audio: Add quirk for PreSonus AudioBox USBAbhinav Mahadevan
The PreSonus AudioBox USB (0x194f:0x0301) only supports S24_3LE format for both playback and capture. It does not support S16_LE despite being a USB full-speed device. Add explicit format quirks for both the playback (interface 2) and capture (interface 3) interfaces to ensure correct format negotiation.

Much like commit 19f953e74356 ("fbdev: fb_pm2fb: Avoid potential divide by zero error"), we also need to prevent that same crash from happening in the udlfb driver as it uses pixclock directly when dividing, which will crash.

2026-04-10ALSA: interwave: guard PM-only restore helpers with CONFIG_PMCássio Gabriel
The InterWave PM patch added snd_interwave_restore_regs() and snd_interwave_restore_memory() as static helpers, but both are used only from the resume path under CONFIG_PM. On configurations without CONFIG_PM, such as alpha allyesconfig, this leaves both helpers unused and triggers -Wunused-function warnings with W=1. Move the PM-only helpers into the existing CONFIG_PM section. Keep __snd_interwave_restore_regs() outside the guard because it is also used during probe-time initialization.

2026-04-10ALSA: usb-audio: Evaluate packsize caps at the right placeTakashi Iwai
We introduced the upper bound checks of the packet sizes by the ep->maxframesize for avoiding the URB submission errors. However, the check was applied at an incorrect place in the function snd_usb_endpoint_set_params() where ep->maxframesize isn't defined yet; the value is defined at a bit later position. So this ended up with a failure at the first run while the second run works. For fixing it, move the check at the correct place, right after the calculation of ep->maxframesize in the same function.

2026-04-10Bluetooth: hci_qca: Fix BT not getting powered-off on rmmodHans de Goede
The BT core skips calling the hci_dev's shutdown method when the HCI is unregistered. This means that qca_power_off() was not getting called leaving BT powered on. This causes regulators / pwrseq providers to not get disabled which also causes problem when re-loading the module because regulators and pwrseq providers have an enablecount which now has never dropped to 0, causing the BT to not get properly reset between rmmod and re-load which causes initialization failure on the re-load. Fix this by calling qca_power_off() from qca_close() when BT has not already been powered off through a qca_hci_shutdown() call. hci_ldisc.c will call qca_close() after freeing the hdev, so this means that qca_power_off() can now no longer deref hu->hdev, change the logging in qca_power_off() to no longer use hu->hdev.

2026-04-10fwctl: Fix class init ordering to avoid NULL pointer dereference on device ↵Richard Cheng
removal CXL is linked before fwctl in drivers/Makefile. Both use `module_init, so `cxl_pci_driver_init()` runs first. When `cxl_pci_probe()` calls `fwctl_register()` and then `device_add()`, fwctl_class is not yet registered because fwctl_init() hasn't run, causing `class_to_subsys()` to return NULL and skip knode_class initialization. On device removal, `class_to_subsys()` returns non-NULL, and `device_del()` calls `klist_del()` on the uninitialized knode, triggering a NULL pointer dereference.
