Hi Dave,

FYI, the error/warning still remains.

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   2a26d99b251b8625d27aed14e97fc10707a3a81f
commit: 85d1225ec066b2ef46fbd0ed1bae78ae1f3e6c91 drm/i915: Introduce & use new lightweight SGL iterators
date:   5 months ago
config: x86_64-randconfig-s2-10301238 (attached as .config)
compiler: gcc-4.4 (Debian 4.4.7-8) 4.4.7
reproduce:
        git checkout 85d1225ec066b2ef46fbd0ed1bae78ae1f3e6c91
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: it may well be a FALSE warning. FWIW you are at least aware of it now.
