Since auxr_dev has not yet been allocated\non this failure path, the dereference results in a NULL pointer exception\n\nRetrieve the parent bnge_dev from the auxiliary device's parent instead of\nauxr_dev, and free auxr_dev only when it was successfully allocated. This\nallows the release callback to correctly clean up partially initialized\nauxiliary devices."
