3.13.11.6 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Roger Quadros <rogerq@xxxxxx> commit e73b49f1c4e75c44d62585cc3e5b9c7894b61c32 upstream. Prevent resources from being freed twice in case device_add() call fails within phy_create(). Also use ida_simple_remove() instead of ida_remove() as we had used ida_simple_get() to allocate the ida.
