Subject: device property: convert to use match_string() helper
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a7c1d0a987ee3be0b87db5c95aa4fbadf7c3c1c2;p=deliverable%2Flinux.git

device property: convert to use match_string() helper

The new helper returns index of the mathing string in an array.  We
would use it here.
