Patch needs a drm/gma500: prefix in the summary. Also please list in the
commit message itself what kinds of warnings exactly you've fixed. Most
maintainers also want that you split the patch up into one addressing each
issue separately (e.g. one for whitespace, one for printk, one for != NULL
removal).
