 When the time comes for Xe, the protection will be lifted on Xe and kept in i915.
 
-Xe driver will be protected with both STAGING Kconfig and force_probe. Changes in
-the uAPI are expected while the driver is behind these protections. STAGING will
-be removed when the driver uAPI gets to a mature state where we can guarantee the
-‘no regression’ rule. Then force_probe will be lifted only for future platforms
