Thomas, Looking at the fb.h file I see: struct device *device; /* This is the parent */ struct device *dev; /* This is this fb device */ Is this documentation "correct"? If so, how does that match what you are doing here? Thanks, M > } > > static const struct backlight_ops bd6107_backlight_ops = { >-- >2.41.0
