The irq_to_gpio function was removed from the pxa platform
in linux-3.2, and this driver has been broken since.
Without this patch, building raumfeld_defconfig results in:
drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active':
drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of
function 'irq_to_gpio' [-Werror=implicit-function-declaration]
