drm/rockchip: dw_hdmi: Use resume_early pm ops for system suspend ...
rockchip_drm_sys_resume()/drm_mode_config_helper_resume() is called
before the resume pm ops of dw-hdmi. This result in an atomic_enable()
before dw_hdmi_rockchip_resume()/dw_hdmi_resume() is called.
Resume (without changes):
- rockchip_drm_sys_resume()
- drm_mode_config_helper_resume()
- atomic_enable()
- dw_hdmi_rockchip_resume()
- dw_hdmi_resume()
- dw_hdmi_init_hw()
Change to use resume_early pm ops for system suspend to ensure pm ops
for dw-hdmi is run before rockchip-drm pm ops. Also fix a possible NULL
pointer dereference timing issue while at it.
Resume (with changes):
- dw_hdmi_rockchip_resume_early()
- dw_hdmi_resume()
- dw_hdmi_init_hw()
- rockchip_drm_sys_resume()
- drm_mode_config_helper_resume()
- atomic_enable()
