Description

net: dsa: microchip: Don't free uninitialized ksz_irq

In the Linux kernel, the following vulnerability has been resolved:

net: dsa: microchip: Don't free uninitialized ksz_irq

If something goes wrong at setup, ksz_irq_free() can be called on

uninitialized ksz_irq (for example when ksz_ptp_irq_setup() fails). It

leads to freeing uninitialized IRQ numbers and/or domains.
