Implementing suspend/resume functionality in componentized drm drivers using master component PM callbacks is problematic because those callbacks can be called asynchronously regardless of existence/state of drm device. The patch re-enables suspend/resume drm driver callbacks in drivers with modeset feature enabled. These callback can be used to implement suspend/resume functionality in more convenient way. The patch should not affect behavior of existing drm drivers.
