Subject: expo: Convert to using a string ID for the scene title
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=def898c458e65a71fb64cda370b4281cd026e48c;p=u-boot.git

expo: Convert to using a string ID for the scene title

This is easier to deal with if it uses the existing string handling,
since we will be able to use translations, etc. in the future.

Update it to use an ID instead of a string.
