I'll move it into include/linux/input/cy8ctmg110_pdata.h and kill some useless comments and will apply to next, thanks Alan.

Hmm, I think device_init_wakeup() call is missing as well. And threaded IRQ being chared is somewhat unusual... But it is not oneshot so should be OK.

I will double check these. I don't believe the IRQ can ever get shared but I'd need to double check with the Aava folks.
