Subject: hwmon: (ad7314) Adds missing spi_dev initialization
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e16de9137c8beab02d78fb4fa82bb96e9f3d0ac3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

hwmon: (ad7314) Adds missing spi_dev initialization

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.
