- * Keep those macros in sync with those in
- * include/linux/usb/composite.h or else GCC will complain. If they
- * are identical (the same names of arguments, white spaces in the
- * same places) GCC will allow redefinition otherwise (even if some
- * white space is removed or added) warning will be issued.
- *
- * Those macros are needed here because File Storage Gadget does not
- * include the composite.h header. For composite gadgets those macros
- * are redundant since composite.h is included any way.
- *
- * One could check whether those macros are already defined (which
- * would indicate composite.h had been included) or not (which would
- * indicate we were in FSG) but this is not done because a warning is
- * desired if definitions here differ from the ones in composite.h.
- *
- * We want the definitions to match and be the same in File Storage
- * Gadget as well as Mass Storage Function (and so composite gadgets
- * using MSF). If someone changes them in composite.h it will produce
- * a warning in this file when building MSF.
