When doing a modeset operation, the wait is still uninterruptible. But considering that failing to turn off the overlay when switching off the crtc it's running on hangs the chip, it doesn't complicate matters _very_ much. There's just an unkillable X in addition to a black screen. BUG() about it and explain in the code. Signed-off-by: Daniel Vetter Signed-off-by: Eric Anholt --- Reading git-diff-tree failed
