CVE-2026-98564 net: dsa: mt7530: leave the MDIO IRQ mappings to regmap-irq

In the Linux kernel, the following vulnerability has been resolved: net: dsa: mt7530: leave the MDIO IRQ mappings to regmap-irq mt7530removecommon disposes the per-PHY interrupt mappings from .remove, but the regmap-irq chip that owns the domain is devm-registered, so its parent interrupt is only...
