[PATCH 3.19.y-ckt 10/86] hwmon: (nct6775) Swap STEP_UP_TIME and STEP_DOWN_TIME registers for most chips

[Kamal Mostafa]

3.19.8-ckt9 -stable review patch.  If anyone has any objections, please let me know.

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

From: Guenter Roeck <linux at roeck-us.net>

commit 728d29400488d54974d3317fe8a232b45fdb42ee upstream.

The STEP_UP_TIME and STEP_DOWN_TIME registers are swapped for all chips but
NCT6775.
