Subject: hwmon: (lm70) Simplify show_name function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=860f37319e9a1141b041ca2e77ca121dccde4b93;p=linux-beck.git

hwmon: (lm70) Simplify show_name function

Instead of using a switch statement to determine the device name, use
to_spi_device(dev)->modalias to simplify the code and reduce module size.
