Subject: [PATCH v2 5/7] Bluetooth: btintel: Add support to fetch data path id for a2dp offload
Date:   Fri,  8 Oct 2021 19:37:57 +0530
Message-Id: <20211008140759.15493-5-kiran.k@intel.com>
In-Reply-To: <20211008140759.15493-1-kiran.k@intel.com>
References: <20211008140759.15493-1-kiran.k@intel.com>
Precedence: bulk
