I wondered about that too, gcc doesn't even warn when the two values are
different. See for example commit
bd9e310dca15c9987256f67af19f9f42426e7493.

I already submitted a patch for the imx bits with Message id
1335989287-10094-1-git-send-email-u.kleine-koenig@pengutronix.de.
(e.g.
http://mid.gmane.org/1335989287-10094-1-git-send-email-u.kleine-koenig@pengutronix.de)

Don't know if Sascha took it already. If he did, he didn't tell me.

Best regards
