Hello Yue,
Shouldn't the tegra_vde_runtime_resume() be marked as well?

Well.. it's unused, but compiler doesn't complain about runtime_resume()
because it sees the potential reference to that function in the code
(even that it's a dead code), while runtime_suspend() reference is
completely removed by preprocessor before compiler sees the code.
Should be nicer to have both suspend and resume functions marked, for
consistency, IMO.
