In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: release hif2 reference on probe IRQ failure
The hif2 reference obtained by mt7915_pci_init_hif2() is only released on
error paths that key off dev->hif2, which is not assigned until after the
IRQ setup. If pci_alloc_irq_vectors() or the primary devm_request_irq()
fails, the reference leaks. Drop it explicitly on those paths via
mt7915_put_hif2().
