CVE-2026-93276

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

phy: renesas: phy-rcar-gen3-usb2: Fix devm action registration for disabled VBUS regulator

devm regulator get exclusive() initialises the regulator with enable count = 1, requiring the consumer to disable it before release.

The devm disable action was previously only registered when the caller explicitly requested enable, so when the regulator was left in its initial enabled state without an explicit enable call, the cleanup path skipped decrementing enable count, triggering a WARN ON during regulator release on device removal.

Fix this by always registering the devm disable action based on the actual enabled state via regulator is enabled(), regardless of whether the caller requested an explicit enable. This covers both the explicitly enabled case and the initial state set by devm regulator get exclusive().
