I've already fixed this part in my code, and will be pushing it upstream as soon as the input GIT tree gets merged by Linus. > In my case result_aux is 0 due to my BIOS not exporting a PS/2 mouse PNP > id after which the code just assigns the default irq 12 (the first PNP: > line above) but winds up printing "irq 112".
