Dear LM-Sensors,
I have a Dell FS12-NV7 server and it has two W83792G chips on it (as well as
an IT87). One of the W83792G devices is connected to three fans on PWM
outputs 3,4 and 5 respectively.
I am running with Ubuntu 15.04 (Linux 3.19.0) and the W83792D driver only
has support for PWM outputs 1,2 and 3.
The patch below adds the 4 missing PWM outputs which are supported by the
chip. This has been tested and works as expected on my motherboard.

I hope this patch is of use to others who are using the same server or have
a similar situation.
Best regards,
