I spoke too soon. If devm_phy_get fails, we don't set hsotg->phy and probe defer thus not reaching this point.

Same above, this will be NULL on failure (but is only applicable at this point on the platform data path. -Matt -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
