Subject: [PATCH 5/5] drm/amd/display: Remove unused dcn_find_dcfclk_suits_all
From: "Dr. David Alan Gilbert" <linux@...blig.org>
dcn_find_dcfclk_suits_all() last use was removed by 2018's
commit 4fd994c448a3 ("drm/amd/display: Start using the new pp_smu
interface")
Remove it, and the dcn_find_normalized_clock_vdd_Level helper it used.
Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
