Instead of having every video driver loop over any pending leases to free them during CloseScreen, do this up in the DIX layer by terminating leases when a leased CRTC or Output is destroyed and (just to make sure), also terminating leases in RRCloseScreen. The latter should "never" get invoked as any lease should be associated with a resource which was destroyed. This is required as by the time the driver's CloseScreen function is invoked, we've already freed all of the DIX randr structures and no longer have any way to reference the leases Signed-off-by: Keith Packard <keithp@keithp.com> Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=106960 Cc: Thomas Hellstrom <thellstrom@vmware.com>
