The driver incorrectly uses gpiod_set_value() instead of gpiod_set_value_cansleep() for reset GPIO operations. This can lead to system warnings when the reset GPIO is managed by a sleeping controller, potentially causing unexpected behavior or instability during the probe path.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80999.json)\n\n**kernel: net: dsa: realtek: use gpiod_set_value_cansleep for reset GPIO** — rated Moderate by Red Hat.
