I suggest you do a build of the affected drivers after adding this patch
to make sure you have changed all mode -> legacy_mode occurrences
_before_ adding back mode in a later patch.

A simple grep gave me these:

drivers/gpu/drm/vc4/vc4_vec.c:
vc4_vec_tv_modes[state->tv.mode].mode);
drivers/gpu/drm/vc4/vc4_vec.c: vec->tv_mode =
&vc4_vec_tv_modes[conn_state->tv.mode];
drivers/gpu/drm/vc4/vc4_vec.c: vec_mode =
&vc4_vec_tv_modes[conn_state->tv.mode];
drivers/gpu/drm/i915/display/intel_tv.c: int format =
conn_state->tv.mode;
drivers/gpu/drm/i915/display/intel_tv.c:
connector->state->tv.mode = i;
drivers/gpu/drm/i915/display/intel_tv.c: if (old_state->tv.mode
!= new_state->tv.mode ||
drivers/gpu/drm/i915/display/intel_tv.c: state->tv.mode =
initial_mode;
drivers/gpu/drm/i915/display/intel_tv.c:
state->tv.mode);
drivers/gpu/drm/i915/display/intel_sdvo.c: format_map = 1 <<
conn_state->tv.mode;
drivers/gpu/drm/i915/display/intel_sdvo.c: format_map = 1 <<
conn_state->tv.mode;
drivers/gpu/drm/i915/display/intel_sdvo.c: if
(state->tv.mode == intel_sdvo_connector->tv_format_supported[i]) {
drivers/gpu/drm/i915/display/intel_sdvo.c: state->tv.mode =
intel_sdvo_connector->tv_format_supported[val];
drivers/gpu/drm/i915/display/intel_sdvo.c:
intel_sdvo_connector->base.base.state->tv.mode =
intel_sdvo_connector->tv_format_supported[0];

Not so easy to grep for is this in gud:

static unsigned int *gud_connector_tv_state_val(u16 prop, struct
drm_tv_connector_state *state)
{
switch (prop) {
...
case GUD_PROPERTY_TV_MODE:
return &state->mode;
