Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() to avoid
device usage counter leak.

Applied, thanks!

[1/1] drm/rockchip: use pm_runtime_resume_and_get() instead of pm_runtime_get_sync()
      commit: e3558747ebe15306e6d0b75bd6d211436be4a7d5

I've dropped the lvds part and used the separate patch from your
Huawei-collegue Zhang Qilong

Best regards,
