Subject: [PATCH v3 1/2] Bluetooth: btnxpuart: Simplify nxp_recv_acl_pkt() by hci_acl_handle()
Date: Tue, 15 Sep 2026 19:17:17 -0700	[thread overview]
Message-ID: <20260915-misc_fix-v3-1-31fab8976ac1@oss.qualcomm.com> (raw)
In-Reply-To: <20260915-misc_fix-v3-0-31fab8976ac1@oss.qualcomm.com>

Simplify nxp_recv_acl_pkt() by using hci_acl_handle() instead of:

__u16 handle = __le16_to_cpu(hci_acl_hdr(skb)->handle);
... (handle & 0x0FFF) ...
