Re: [U-Boot] [PATCH 2/2] api: export LCD and video to external apps

Dear Che-liang Chiou,

What happens here if no display is available?

It is equivalent to a no-op. Or do you think we should print a warning message if no display is available?

Please either add an if() and don;t run the function at all, or add a comment that explains that this callis harmless if no display is present.

Best regards,

Wolfgang Denk
