From: Sandor Yu <Sandor.yu@xxxxxxx>
In function malidp_crtc_mode_valid, mode->crtc_mode = 0 when run
in drm_helper_probe_single_connector_modes.
Invalid video modes are not culled
and all modes move to the connector's modes list.
It is not expected by mode_valid.
Replace mode->crtc_clock with mode->clock to fix the issue.
