- Use standard convention to define ioctls. Currently 0xDB is used as identifier for dspbridge. Discussion: http://marc.info/?l=linux-omap&m=126297631603035&w=2 WARNING: An update in api ioctl definitions is required, usually replacing to a new libbridge (with ioctl patch) should be enough. Other clients (not using libbridge) need to update their ioctl numbers manually.
