reverted the inverted row pins, the issue was not one of active_low/active_high, but an incomplete transition to using column pins for input and row pins for output. everything works except for columns 7 and 9(pins 15 and 4)

which are always held detected as hgih. testing with the /sysfs interface has shown that pin 4 is electrically sound so it must be an issue with the driver# Please enter the commit message for your changes. Lines starting
