The commit 0f40ba48de3b ("drm/msm/dsi: Pass DSC params to drm_panel")
added a pointer to the DSC data to the struct drm_panel. However DSC

consume DSC command streams. Thus add struct drm_dsc_config pointer to
the struct mipi_dsi_device.

Agreed, DSC params are not limited to a drm_panel. From that standpoint, this change seems logical to me, hence
