    Subject[PATCH v2] scripts: add typdef removal tool
    Date
    If you are porting drivers and need to remove tydpefs you can use
    this to help you port the driver faster. Until we don't have a fully
    correct and complete way to do this through Coccinelle spatch we
    might as well help developers porting drivers with something. spatch
    also has a learning curve, people working on staging may not end
    up using it for a while.
