Increase the timeout for vblank events from 100 ms to 1000 ms. This
is the same fix as in commit f050da08a4ed ("drm/vblank: Increase
timeout in drm_wait_one_vblank()") for another vblank timeout.After merging generic DRM vblank timers [1] and converting several DRM drivers for virtual hardware, these drivers synchronize their vblank events to the display refresh rate. This can trigger timeouts within the DRM framework.
