Subject: [PATCH] Bluetooth: btusb: Do not call kfree_skb() under spin_lock_irqsave()
Git-commit: 2a05334d7f91ff189692089c05fc48cc1d8204de
Patch-mainline: v6.6-rc1
References: git-fixes
It is not allowed to call kfree_skb() from hardware interrupt
context or with hardware interrupts being disabled.
So replace kfree_skb() with dev_kfree_skb_irq() under
spin_lock_irqsave(). Compile tested only.
Fixes: baac6276c0a9 ("Bluetooth: btusb: handle mSBC audio over USB Endpoints")
