Subject: device property: Use multi-connection matchers for single case
X-Git-Tag: v6.6.17~7346^2~78
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bcd6a517aacae7e708a1be019a0c3ab9f4371c2b;p=platform%2Fkernel%2Flinux-rpi.git

device property: Use multi-connection matchers for single case

The newly introduced helpers for searching for matches in the case of
multiple connections can be resused by the single-connection case, so do
this to save some duplication.
