If anyone has any objections, please let me know. ------------------ From: Kars de Jong <jongk@...ux-m68k.org> commit e34494c8df0cd96fc432efae121db3212c46ae48 upstream. The driver was reading the wrong register as the 10-hour digit due to a misplaced ')'. It was in fact reading the 1-second digit register due to this bug. Also remove the use of a magic number for the hour mask and use the define for it which was already present.
