- * - device=major,minor specifies the device number used for /dev/drm
- * - if major == 0 then the misc device is used
- * - if major == 0 and minor == 0 then dynamic misc allocation is used
- * - debug=on specifies that debugging messages will be printk'd
- * - debug=trace specifies that each function call will be logged via printk
- * - debug=off turns off all debugging options
- *
- * \todo Actually only the \e presence of the 'debug' option is currently
