Subject: [ 019/102] hwmon: (max6697) fix MAX6581 ideality

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

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

From: Vivien Didelot <vivien.didelot@...oirfairelinux.com>

commit 5c52add19733eb36d8619713312f5604efef3502 upstream.

Without this patch, the values for ideality (register 0x4b) and ideality
selection mask (register 0x4c) are inverted.
