X-Git-Tag: v6.6.7~2016^2~44^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b68adc0ee5b5d12e6eb683e523f1158dabd19f43;p=platform%2Fkernel%2Flinux-starfive.git

iio: potentiometer: mcp4018: Use i2c_get_match_data()

Replace of_device_get_match_data() and i2c_match_id() by i2c_get_match
_data() by making similar I2C and DT-based matching table.
