This patch fixes access issue to invalid memory region.
crtc had only one drm_framebuffer object so when framebuffer
cleanup was requested after page flip, it'd try to disable
hardware overlay to current crtc.
But if current crtc points to another drm_framebuffer,
This may induce invalid memory ac

This patch fixes access issue to invalid memory region.
crtc had only one drm_framebuffer object so when framebuffer
cleanup was requested after page flip, it'd try to disable
hardware overlay to current crtc.
But if current crtc points to another drm_framebuffer,
This may induce invalid memory ac
