[Qemu-devel] [PATCH v10 1/9] tpm-backend: Remove unneeded member variable from backend class

[Amarnath Valluri <amarnath.valluri@intel.com>]

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.
