X-Received-From: 134.134.136.65 Subject: [Qemu-devel] [PATCH v2 1/9] tpm-backend: Remove unneeded member variable from backend class X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Amarnath Valluri , patrick.ohly@intel.com, marcandre.lureau@gmail.com, stefanb@linux.vnet.ibm.com Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP TPMDriverOps inside TPMBackend is not required, as it is supposed to be a class member. The only possible reason for keeping in TPMBackend was, to get the backend type in tpm.c where dedicated backend api, tpm_backend_get_type() is present.
