Hello,

These patches add a hwmon driver for the integrated fan control module
in the Delta AHE-50DC Open19 power shelf.  I don't know of a datasheet
any proper documentation for it; the register layout information came
from an existing GPL driver [0] in a code release from LinkedIn.

(Re-sending a v2 after noticing an embarrassing oversight I missed
before sending v1.)


Thanks,
Zev Weiss

Changes since v1 [1]:
 - fixed invalid name warning from __hwmon_device_register()
