The res pointer passed to simpledrm_device_release_clocks() and simpledrm_device_release_regulators() points to an instance of struct simpledrm_device. No need to upcast from struct drm_device. The upcast is harmless, as DRM device is the first field in struct simpledrm_device.
Thanks, it looks good to me.
