Close for EE RC5

Thanks.  Initially this was an error. Ronan cherry picked using command line so it does not show up in gerrit. 

The commit has been cherry-pick to eel branch.

@Stephane Desneux Please check. I did a search in gerrit for https://lf-automotivelinux.atlassian.net/browse/SPEC-1151#icft=SPEC-1151 and found that 12305 has not been cherry picked to eel.  12307 somehow does not have the https://lf-automotivelinux.atlassian.net/browse/SPEC-1151#icft=SPEC-1151 indication on it, but it looks ok.
