[Intel-gfx] [PATCH 09/12] drm: Shrink drm_display_mode timings

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Store the timings (apart from the clock) as u16. The uapi mode
struct already uses u16 for everything so using something bigger
internally doesn't really help us.
