CVE-2026-90352

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().
