The heavy lifting will then be done by the drm_mode_create_from_cmdline_mode() function. In the case of the named modes though, there's no real code to make that translation and we rely on the drivers to guess which actual display mode we meant. Let's modify drm_mode_create_from_cmdline_mode() to properly generate the drm_display_mode we mean when passing a named mode.
