ACPI: pfr_update: Fix the driver update version check
Published Sep 5, 2025

HIGHCVSS 3.1
EPSS 0.19%
Description
The security-version-number check should be used rather than the runtime version check for driver updates.
Otherwise, the firmware update would fail when the update binary had a lower runtime version number than the current one.
