  Message : Use override in all the places where it is possible This will avoid -Winconsistent-overrides in the future. Done using the -Wsuggest-override warning of GCC 5.1 BUG= Change-Id: I707a649dc368f5dd1e139fd144370abcac0b6263 Reviewed-on: https://chromium-review.googlesource.com/294920 Reviewed-by: Jamie Madill <jmadill@chromium.org> Tested-by: Corentin Wallez <cwallez@chromium.org>
