    Subject[PATCH 4.14 426/496] drm/panel: simple: Fix the bus format for the Ontat panel
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Eric Anholt <eric@anholt.net>

    [ Upstream commit 5651e5e094591f479adad5830ac1bc45196a39b3 ]

    This fixes bad color output. When I was first testing the device I
    had the DPI hardware set to 666 mode, but apparently in the refactor
    to use the bus_format information from the panel driver, I failed to
    actually update the panel.
