Hi Dan,

Thanks for the review.

This was found through static analysis by Yuhao Jiang.

I don't have SM750 hardware to test on, but verified by code inspection
that the fix is consistent with how other fbdev drivers handle this case.

There is no bug tracker entry for this, so no Closes tag.

Thanks,
Junrui Luo
