We cannot reference priv->fbdev outside of the #ifdef:

Since the code is moved into the main probe function now, this adds another #ifdef.

Thanks for catching this.

Could we instead stop compling out priv->fbdev? There's nothing driver-specific here, so teh #ifdef are kinda annoying ... And saving that one pointer in a really huge structure is somewhat silly.
return 0;

poll helpers aren't fbdev specific. Why do we need this? Is this just to shut up gcc?
Thanks, Daniel
