Subject: [PATCH] Bluetooth: btusb: Remove detection of ISO packets over bulk
References: bsc#1012628
Patch-mainline: 6.2.9
Git-commit: efe375b716c1c1c9b52a816f5b933a95421020a2
[ Upstream commit efe375b716c1c1c9b52a816f5b933a95421020a2 ]
This removes the code introduced by
14202eff214e1e941fefa0366d4c3bc4b1a0d500 as hci_recv_frame is now able
to detect ACL packets that are in fact ISO packets.
Fixes: 14202eff214e ("Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packet")
