Re: [PATCH v3 3/4] drm/connector: Split out orientation quirk detection

Hi,

On 22-06-19 05:41, Derek Basehore wrote:
Not every platform needs quirk detection for panel orientation, so
split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.

The above chunk seems to be a leftover from the previous version of this series.

Otherwise this patch looks good, with this fixed you can add my:
