In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Add vblank register/unregister callback functions
We encountered a kernel panic issue that callback data will be NULL when it's using in ovl irq handler. There is a timing issue between mtk_disp_ovl_irq_handler() and mtk_ovl_disable_vblank().
To resolve this issue, we use the flow to register/unregister vblank cb: - Register callback function and callback data when crtc creates. - Unregister callback function and callback data when crtc destroies.
With this solution, we can assure callback data will not be NULL when vblank is disable.
