The BUG_ON() checks in comedi_subdevice_from_minor() and comedi_dev_get_from_subdevice_minor() are not necessary. The 'minor' numbers for a given comedi driver are setup by comedi_dev_get_from_subdevice_minor() and will always be in the correct range. Drivers should not crash the kernel, remove the BUG_ON() checks.
