drm/msm: dpu: Grab the modeset locks in frame_event
This patch wraps dpu_core_perf_crtc_release_bw() with modeset locks since it digs into the state objects. Changes in v2: - None Changes in v3: - Use those nifty new DRM_MODESET_LOCK_ALL_* helpers (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jeykumar Sankaran <jsanka@codeaurora.org> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
