Use another number to request a different interrupt line, or avoid loading the driver that takes exclusive control of that line. WebFollow the sections maked with TODO 1 in the skeleton. Request the I/O ports in kbd_init () and make sure to check for errors and to properly clean-up in case of errors. When requesting, set the reserving caller's ID string ( name) with MODULE_NAME macro. Also, add code to release the I/O ports in kbd_exit ().
