[ 17/38] hwmon: (w83627ehf) Force initial bank selection

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Jean Delvare <khali@xxxxxxxxxxxx>

commit 3300fb4f88688029fff8dfb9ec0734f6e4cba3e7 upstream.

Don't assume bank 0 is selected at device probe time. This may not be
the case. Force bank selection at first register access to guarantee
that we read the right registers upon driver loading.
