Subject[PATCH 4.9 160/171] drm/edid: Add 6 bpc quirk for BOE panel in HP Pavilion 15-n233sl
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

commit 0711a43b6d84ff9189adfbf83c8bbf56eef794bf upstream.

There's another panel that reports "DFP 1.x compliant TMDS" but it
supports 6bpc instead of 8 bpc.

Apply 6 bpc quirk for the panel to fix it.
