Subject: hwmon: Avoid initializing the same field twice
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cf0a91ebe11cee1df871619af4eb58c9af32666;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

hwmon: Avoid initializing the same field twice

All hwmon drivers allocate their data structure with some form of
kzalloc, so setting data fields to zero explicitly is a waste of time.
