[Qemu-devel] [PATCH] tpm: add stubs for qdev-prop-tpm

[Cornelia Huck <cohuck@redhat.com>]

Building with --disable-tpm yields

../hw/core/qdev-properties-system.o: In function `set_tpm':
/home/cohuck/git/qemu/hw/core/qdev-properties-system.c:274: undefined reference to `qemu_find_tpm_be'
/home/cohuck/git/qemu/hw/core/qdev-properties-system.c:278: undefined reference to `tpm_backend_init'
../hw/core/qdev-properties-system.o: In function `release_tpm':
/home/cohuck/git/qemu/hw/core/qdev-properties-system.c:291: undefined reference to `tpm_backend_reset'

Add some proper stubs for those functions.

Fixes: 493b78303532 ("qdev: add DEFINE_PROP_TPMBE")
