From efe375b716c1c1c9b52a816f5b933a95421020a2 Mon Sep 17 00:00:00 2001 From: Luiz Augusto von Dentz Date: Fri, 24 Feb 2023 15:54:31 -0800 Subject: [PATCH] Bluetooth: btusb: Remove detection of ISO packets over bulk This removes the code introduced by 14202eff214e1e941fefa0366d4c3bc4b1a0d500 as hci_recv_frame is now able to detect ACL packets that are in fact ISO packets.
