X-Git-Tag: v5.15~7708^2~3^2~58 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=4a0ad70d690c9bc13f691993da0f38b8634d7eeb;p=mirror_ubuntu-kernels.git drm/amd/display: fix Interlace video timing. [Description] interlace mode shows wrong vertical timing. Interface timing in Edid is half vertical timing as progressive timing. driver doubled the vertical timing in edid_paser, no need to double in optc again.
