[PATCH 1/2] drm/atomic: Consitfy mode parameter to drm_atomic_set_mode_for_crtc()

[PATCH 1/2] drm/atomic: Consitfy mode parameter to drm_atomic_set_mode_for_crtc()

[ville.syrjala]

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

drm_atomic_set_mode_for_crtc() doesn't modify the passed mode, so let's
make it const.

[PATCH 2/2] drm/i915: Constify load detect mode

[ville.syrjala]

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

Make the mode used for load detection const, and adjust all relevant
functions to accept a const mode.
