Subject: [PATCH 4/4] xkb: ignore floating slave devices when updating from
 master (#81885)

Introduced in 45fb3a934dc0db51584aba37c2f9d73deff9191d. When a device is
enabled, the master's locked state is pushed to the slave. If the device is
floating, no master exists and we triggered a NULL-pointer dereference
in XkbPushLockedStateToSlaves.
