        Avoid applying operator -> to m_imageResource when its underlying pointer is NULL.

        * rendering/RenderImage.h:
        (WebCore::RenderImage::intrinsicSizeChanged): Checked m_imageResource.
        * html/HTMLImageElement.cpp:
        (HTMLImageElement::createRenderer): Fixed indentation.
