[PATCH 6.6.y] Revert "usb: phy: fsl-usb: Fix use-after-free in delayed work during device removal"

From: Ralf Lici <hidden>
Date: 2026-08-28 07:27:48
Also in: linux-usb, lkml, stable
Subsystem: freescale usb phy driver, the rest, usb subsystem · Maintainers: Linus Torvalds, Greg Kroah-Hartman

This reverts commit 319f7a85b3c4e34ac2fe083eb146fe129a556317.

The reverted commit uses disable_delayed_work_sync, which was introduced
by commit 86898fa6b8cd ("workqueue: Implement disable/enable for
(delayed) work items") in v6.10. The function is therefore unavailable
in 6.6.y, causing configurations that enable CONFIG_FSL_USB2_OTG to fail
to build.

The upstream commit is unaffected; only its incompatible stable backport
is being reverted.

Fixes: 319f7a85b3c4 ("usb: phy: fsl-usb: Fix use-after-free in delayed work during device removal")
