Hm... I didn't followed the state machine all the way through so I'm not actually sure how this is called. But it's weird that priv->phydev is initialized on the left side of the assignment but dereferenced in the function mentioned on the right side if the assignment. Also this patch should not be marked as "trivial" in the subject. "trivial" is only for spelling mistakes in comments etc. regards, dan carpenter _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
