[PATCH] staging/iio: iio_hwmon: Use device tree node name for hwmon name attribute

From: Guenter Roeck
Date: Wed Mar 20 2013 - 11:52:49 EST

So far, all instances of iio_hwmon set their hwmon name attribute
to "iio_hwmon", which is not very descriptive. Set it to the device tree
node name if available, and only revert to iio_hwmon otherwise.

Jonathan, can we move this driver out of staging ?
I would like to see it in 3.10 if possible.
