In the function panel_simple_probe() the pointer panel->desc is assigned to the passed pointer desc. If function panel_dpi_probe() is called panel->desc will be updated, but further on only desc will be evaluated. So update the desc pointer to be able to use the data from the function panel_dpi_probe().Fixes: 4a1d0dbc8332 ("drm/panel: simple: add panel-dpi support") Signed-off-by: Christoph Niedermaier <cniederma...@dh-electronics.com> Cc: Marek Vasut <ma...@denx.de> Cc: Thierry Reding <thierry.red...@gmail.com> Cc: Sam Ravnborg <s...@ravnborg.org> Cc: David Airlie <airl...@linux.ie> Cc: Daniel Vetter <dan...@ffwll.ch> To: dri-devel@lists.freedesktop.org --- drivers/gpu/drm/panel/panel-simple.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/panel/panel-simple.c b/drivers/gpu/drm/panel/panel-simple.c index 9e46db5e359c..3c08f9827acf 100644 --- a/drivers/gpu/drm/panel/panel-simple.c +++ b/drivers/gpu/drm/panel/panel-simple.c @@ -588,6 +588,7 @@ static int panel_simple_probe(struct device *dev, const struct panel_desc *desc) err = panel_dpi_probe(dev, panel); if (err) goto free_ddc; + desc = panel->desc; } else { if (!of_get_display_timing(dev->of_node, "panel-timing", &dt)) panel_simple_parse_panel_timing_node(dev, panel, &dt);
