Randy Dunlap already sent a patch like this one.

I ran into this build failure during randconfig testing: drivers/input/touchscreen/ad7879.c: In function 'ad7879_parse_dt': drivers/input/touchscreen/ad7879.c:505:8: error: implicit declaration of function 'device_property_read_u32' drivers/input/touchscreen/ad7879.c:512:2: error: implicit declaration of function 'device_property_read_u8' drivers/input/touchscreen/ad7879.c:521:16: error: implicit declaration of function 'device_property_read_bool' I could not figure out when this was introduced, as the code doesn't appear to have changed recently, but the fix of including the header with the declaration is obvious. The calls that require the extra header were introduced a year ago in commit fa6e3ca27442 ("Input: ad7879 - add device tree support").
