[PATCH 3.16.y-ckt 058/180] compal-laptop: Fix leaking hwmon device

[Luis Henriques]

3.16.7-ckt11 -stable review patch.  If anyone has any objections, please let me know.

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

From: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>

commit ad774702f1705c04e5fa492b793d8d477a504fa6 upstream.

The commit c2be45f09bb0 ("compal-laptop: Use
devm_hwmon_device_register_with_groups") wanted to change the
registering of hwmon device to resource-managed version. It mostly did
it except the main thing - it forgot to use devm-like function so the
hwmon device leaked after device removal or probe failure.
