Output in dmesg:
[    2.054475] cherryview-pinctrl INT33FF:00: INTMASK0: 0x00000006
[    2.055247] cherryview-pinctrl INT33FF:00: INTMASK1: 0x00000000
[    2.055375] cherryview-pinctrl INT33FF:01: INTMASK0: 0x00004000
[    2.056931] cherryview-pinctrl INT33FF:01: INTMASK1: 0x00000000
[    2.057036] cherryview-pinctrl INT33FF:02: INTMASK0: 0x00000000
[    2.057367] cherryview-pinctrl INT33FF:02: INTMASK1: 0x00000000
[    2.057489] cherryview-pinctrl INT33FF:03: INTMASK0: 0x00000000
[    2.058337] cherryview-pinctrl INT33FF:03: INTMASK1: 0x00000000

So it's somehow got cleared in the process after.

And the following link is the complete /proc/interrupts:

THe interrupt doesn't work is 9, when I made it work it responsed to
pressing hotkeys.
