The helper increments the global hif_idx, writes the\nPCIe RECOG_ID register and takes a get_device() reference via\nmt7915_pci_get_hif2(), while removal only drops one reference. On non-WED\ndual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and\nleaked a device reference. Only the call inside the WED-inactive branch is\ncorrect; drop the unconditional one. hif2 is already initialised to NULL."
