Subject: hwmon: (lm63) Introduce 'dev' variable to point to client->dev
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2fd638feb6b39cbbc10989a57a25c868fe65b118;p=linux-beck.git

hwmon: (lm63) Introduce 'dev' variable to point to client->dev

client->dev is used multiple times in several functions.
Introduce dev variable pointing to it to simplify the code.
