[PATCH v3 0/5] Bluetooth: btusb: fix wakeup irq devres lifetime
From: Johan Hovold
Date: Thu Apr 02 2026 - 11:56:32 EST
This series fixes a couple of use-after-free issues and a wakeup source
leak on probe failure and a (currently benign) OOB wakeup interrupt
devres lifetime issue.
Included is also a related cleanup.
Note that these are intended for 7.1 (e.g. as the fixes are not
critical) and apply on top of linux-next which has commit 2db5a8b68e31
("Bluetooth: btusb: refactor endpoint lookup").
