.load hook is called after all components are attached to the master. So if suspend happen after probe of the master and before attaching the last component you will have NULL here, I guess.
Probably you can test it by disabling driver for one of drm components and putting board in sleep mode.
Moreover I guess drvdata should be cleaned in .unload callback, otherwise if for some reason one of components will be detached and suspend happens drvdata will contain invalid pointer.
You're right, Andrzej. I will fix it in v3. Thanks for the comment.
