Subject: [PATCH] Bluetooth: Add missing checks for HCI_ISODATA_PKT packet type
Git-commit: cc974003615afa044fa62c7520ae690091fa684a
Patch-mainline: v5.6-rc1
References: jsc#SLE-13430
The checks for HCI_ISODATA_PKT packet type are required in a few
additional locations to allow sending/receiving of this new packet type.
