Subject: [PATCH] Bluetooth: hci_qca: don't call kfree_skb() under spin_lock_irqsave()
Git-commit: df4cfc91208e0a98f078223793f5871b1a82cc54
Patch-mainline: v6.2-rc1
References: git-fixes
It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So replace kfree_skb()
with dev_kfree_skb_irq() under spin_lock_irqsave().
