From df4cfc91208e0a98f078223793f5871b1a82cc54 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Wed, 7 Dec 2022 10:18:30 +0800 Subject: Bluetooth: hci_qca: don't call kfree_skb() under spin_lock_irqsave() 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().
