3.16.82-rc1 review patch. If anyone has any objections, please let me know.

From: Kars de Jong jongk@linux-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.
