hwmon: (ad7314) Adds missing spi_dev initialization
Graeme Smecher [Tue, 3 Apr 2012 23:42:21 +0000 (19:42 -0400)]
This driver was recently moved from IIO (where it worked) to hwmon (where
it doesn't.) This breakage occured because the hwmon version neglected to
correctly initialize a reference to spi_dev in its drvdata. The result is a
segfault every time the temperature is queried.
