Maarten Lankhorst 933b9b11f7 drm/i915: Always recompute watermarks when distrust_bios_wm is set, v2. ... commit 4e3aed8445 upstream. On some systems there can be a race condition in which no crtc state is added to the first atomic commit. This results in all crtc's having a null DDB allocation, causing a FIFO underrun on any update until the first modeset. Changes since v1: - Do not take the connection_mutex, this is already done below.
