    device.h: audit and cleanup users in main include dir · 313162d0
    Paul Gortmaker authored
    
    The <linux/device.h> header includes a lot of stuff, and
    it in turn gets a lot of use just for the basic "struct device"
    which appears so often.
    
    Clean up the users as follows:
    
    1) For those headers only needing "struct device" as a pointer
    in fcn args, replace the include with exactly that.
    
    2) For headers not really using anything from device.h, simply
    delete the include altogether.
    
    3) For headers relying on getting device.h implicitly before
    being included themselves, now explicitly include device.h
    
    4) For files in which doing #1 or #2 uncovers an implicit
    dependency on some other header, fix by explicitly adding
    the required header(s).
    
    Any C files that were implicitly relying on device.h to be
    present have already been dealt with in advance.
    
    Total removals from #1 and #2: 51.  Total additions coming
    from #3: 9.  Total other implicit dependencies from #4: 7.
    
    As of 3.3-rc1, there were 110, so a net removal of 42 gives
    about a 38% reduction in device.h presence in include/*
