Subject: drm/msm/dp: simplify dp_connector_get_modes()
Git-commit: a52bfaf614e702a04f4dd4ddf331f8923e29b15f
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Since dp_panel_get_modes() handling for dp_mode was removed,
dp_display_get_modes also doesn't change the passed dp_mode, drop the
unused dp_mode variable being allocated unused and then freed.
