    OMAPDSS: Fix crash with DT boot · 591a0ac7
    Tomi Valkeinen authored
    When booting with DT, there's a crash when omapfb is probed. This is
    caused by the fact that omapdss+DT is not yet supported, and thus
    omapdss is not probed at all. On the other hand, omapfb is always
    probed. When omapfb tries to use omapdss, there's a NULL pointer
    dereference crash. The same error should most likely happen with omapdrm
    and omap_vout also.
    
    To fix this, add an "initialized" state to omapdss. When omapdss has
    been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
    check this state when they are probed to see that omapdss is actually
    there.
