    ecore_drm: pass NULL to mmap() instead 0 for address
    
    The second find of these. The other one was in evas generic loaders.
    mmap() expects a void * as address here. If we want to let the kernel
    choose the address we should really pass in NULL instead of the
    integer 0.
    
    Thanks goes to the sparse semantic parser for pointing this out.
