 Currenlty HDMI fails to come up in the suspend-resume path.
This patch helps that real-world scenario.

What is the problem there? It'd be good to explain the problem in the
patch description. Does the pm_runtime_get return -EACCES?

Yes, it returns -EACCESS because RPM on devices is disabled during the
period from suspend-start to resume-finished.
