net: dsa: microchip: Fix error path in PTP IRQ setup
Published May 8, 2026

MEDIUMCVSS 3.1
EPSS 0.16%
Description
If request_threaded_irq() fails during the PTP message IRQ setup, the newly created IRQ mapping is never disposed. Indeed, the ksz_ptp_irq_setup()'s error path only frees the mappings that were successfully set up.
Dispose the newly created mapping if the associated request_threaded_irq() fails at setup.
