3.2.54-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Brian Carnes <bmcar...@gmail.com>

commit cf7559bc053471f32373d71d04a9aa19e0b48d59 upstream.

The wrong mask is used, which causes some fan speed control modes
(pwmX_enable) to be incorrectly reported, and some modes to be
impossible to set.

[JD: add subject and description.]
