is that we end up processing the buffer overflow over and
over again because the bit is never cleared. Resulting in a random system
lockup because of an infinite loop in an interrupt handler.

nders the system unusable.
[How]
Fix this by erroring out if an error is detected.

[Why]
Similar to commit<0fa375e6>. If the set_state/can_switch code access the
drm_device when dev is not bound,
a null pointer dereference can happen.
[How]
Add sanity checks to prevent it.

[Why]
Similar to commit("drm/amd/display: Guard against null crtc in CRC
IRQ"),
a null pointer deference can occur if crtc is null in
dm_set_vblank.
[How]
Check that CRTC is non-null before accessing its fields.

From: bodefang
Similar to commit <789d4c300>("drm/msm: don't deref error pointer in the
msm_fbdev_create error path")
the error pointer returned by omap_framebuffer_init gets passed to
drm_framebuffer_remove.
The latter handles only Null pointers,thus a nasty crash will occur.
