Subject: [121/152] rtc: rs5c372: fix buffer size

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Wolfram Sang <w.sang@...gutronix.de>

commit 118364948fad7b6c0469ef2d3ddaee447d7a0b5f upstream.

Match the buffer size to the amount of initialized values.  Before, it was
one too big and thus destroyed the neighbouring register causing the clock
to run at false speeds.
