Oleksandr Tymoshenko 108117cc22 [ofw] fix errneous checks for OF_finddevice(9) return value ... OF_finddevices returns ((phandle_t)-1) in case of failure. Some code in existing drivers checked return value to be equal to 0 or less/equal to 0 which is also wrong because phandle_t is unsigned type. Most of these checks were for negative cases that were never triggered so trhere was no impact on functionality.
