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.

It's ok. Just be sure to split the series correctly:
arch/arm/*omap*/ -> to Tony
drivers/mfd/* -> to Samuel
