From: "Dr. David Alan Gilbert" <li...@treblig.org>
mod_freesync_get_vmin_vmax() and mod_freesync_get_v_position() were
added in 2017 by
commit 72ada5f76939 ("drm/amd/display: FreeSync Auto Sweep Support")
mod_freesync_is_valid_range() was added in 2018 by
commit e80e94460841 ("drm/amd/display: add method to check for supported
range")
mod_freesync_get_settings() was added in 2018 by
commit a3e1737ed61c ("drm/amd/display: Implement stats logging")
and
mod_freesync_calc_field_rate_from_timing() was added in 2020 by
commit 49c70ece54b0 ("drm/amd/display: Change input parameter for
set_drr")
None of these have been used.
Remove them.
