Thank you for the patch and for addressing the comment.
But now the commit message is not explaining what's really going on.

Could you please improve the message saying that the function has
changed to static and we don't need doc comment in the static
functions, etc?!

Also, while doing this, please find a better commit message.
This is way to generic. Something like
drm/i915: Remove unnecessary doc from static hwconfig_init
sounds better and easier to understand from a log --oneline.

Oh, and it also looks this patch deserves a "Fixes:" tag,
pointing to the patch that created the mess. Either the original
patch if it already introduced like this, or to the patch that
transformed this function in static. git blame to find the culprit out.

With the commit msg fixed as above I will add my rv-b while merging it.
