    components: multiple components for a device · 3521ee99
    Daniel Vetter authored
    Component framework is extended to support multiple components for
    a struct device. These will be matched with different masters based on
    its sub component value.
    
    We are introducing this, as I915 needs two different components
    with different subcomponent value, which will be matched to two
    different component masters(Audio and HDCP) based on the subcomponent
    values.
    
    v2: Add documenation.
    
    v3: Rebase on top of updated documenation.
    
    v4: Review from Rafael:
    - Remove redundant "This" from kerneldoc (also in the previous patch)
    - Streamline the logic in find_component() a bit.
