"&dsi->connector.state->crtc->state->adjusted_mode;" is too long, and
dsi->connector.state->crtc can be NULL, seems not good.
agree with Chris, I think dsi->mode is better.
Bug the origin code "dsi->mode = adjusted_mode; " also has a bug,
adjusted_mode's lift time is unknown, use a pointer from adjusted_mode
I think we can use like that, copy a display mode to dsi->mode:
- struct drm_display_mode *mode;
+ struct drm_display_mode mode;
