Re: [RESEND 1/3] drm: fsl-dcu: Fix no fb check bug

Hi Stefan,

However, I think with my patch "drm/fsl-dcu: Fix no fb check bug", this situation can be avoided completely: https://lkml.org/lkml/2015/11/18/950

With that patch applied, and a non-existing panel assigned, the DRM driver already fails at probe time gracefully: [ 0.488291] [drm] Initialized drm 1.1.0 20060810 [ 0.501576] fsl-dcu 40058000.dcu: failed to initialize mode setting

So I think that a state->fb check for NULL is not necessary at all...

Can you test my patch to see if it fixes the issue for you too?

This is still required; state->fb being NULL means the plane is being disabled.

Cheers, Daniel
