[PATCHv2 06/31] drm/omap: Init fbdev emulation only when we have displays

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>

Do not try to init the fbdev if either num_crtcs or num_connectors is 0.
In this case we do not have display so the fbdev init would fail anyways.
