No, not with the current mainline. I was just starting to implement some
more helpers there and noticed the issue when including this header from
i915. Then I noticed  Andy and Jani already had similar patches to what
I was doing:

https://lore.kernel.org/all/20210215142137.64476-1-andriy.shevchenko@linux.intel.com/
and https://lore.kernel.org/all/20191023131308.9420-1-jani.nikula@intel.com/

So I'm following up on the first thread abovee to figure out what would
be the proper header to implement this. Meanwhile, we can have this
quick harmless fix.

thanks,
Lucas De Marchi
