Subject: mfd: da9062: Simplify getting of_device_id match data
X-Git-Tag: accepted/tizen/unified/20230118.172025~6893^2~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5783bbe9a434db870891a07cd7826944047368e5;p=platform%2Fkernel%2Flinux-rpi.git

mfd: da9062: Simplify getting of_device_id match data

Use of_device_get_match_data() to make the code slightly smaller.
