[PATCH] gpu: drm: qxl: Fix possible null-pointer dereferences in qxl_crtc_atomic_flush()
...f (crtc->state->active)
and on line 358:
DRM_DEBUG_KMS(..., crtc->state->active, ...);
Thus, possible null-pointer dereferences may occur.
To fix these bugs, crtc->state is checked before calling
qxl_crtc_update_monitors_config().
These bugs are found by a static analysis tool STCheck written by us.
