What is CVE-2026-93225?

Official description
In the Linux kernel, the following vulnerability has been resolved:
phy: fsl-imx8mq-usb: fix typec switch leak on probe error path
If probe fails after imx95_usb_phy_get_tca() succeeds, the typec switch leaks because the only cleanup path was in .remove(), which never runs on probe failure.
Use devm_add_action_or_reset() so the switch is cleaned up on both probe failure and driver removal. The imx95_usb_phy_put_tca() is no longer needed, it will be removed in .remove() too.
