obviously wrong but no wrong behaviour.  Your patch only makes the code
consistent, but IMHO it doesn't qualify as a bugfix.

This conflicts with
http://mid.gmane.org/1290589546-21662-1-git-send-email-u.kleine-koenig@pengutronix.de

which I prefer.  The platform IDs have it correct (i.e.

	imx25-cspi -> 0.7
	imx31-cspi -> 0.4
	imx35-cspi -> 0.7

)

Best regards
Uwe
