+Subject: [PATCH 02/13] mfd: Fix omap_usbhs_alloc_children error handling
+
+1. Return proper error if omap_usbhs_alloc_child fails
+2. In the case of goto err_ehci, we should call platform_device_unregister(ehci)
+   instead of platform_device_put(ehci) because we have already added the
+   platform device to device hierarchy.
