We used a on-demand i915 component binding for IvyBridge and SandyBridge HDMI codecs, but it has a potential problem of the nested module loading. For avoiding that situation, assure the i915 binding happening at the controller driver level for PCH controller devices, where the initialization is performed in a detached work, instead of calling from the codec driver probe.
