I don't know what the right error code is, though. Really I would prefer that MDIO would work even when the device is down, unless you know that all MDIO-manageable devices are powered off.

Can you rebase the patch with latest git repo and resubmit the patch Regards Mugunthan V N -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
