As I noted previously, this works well for drivers that need to access registers with multiple widths, which indeed applies to the vast majority of camera sensor drivers, but not to e.g. flash or lens VCM drivers. Fixed width registers are better served with a width-specific function. But these can be always added later on. -- Sakari Ailus
