Include DMA_BUF regardless of kernel version

[hibby50]

This is causing issues compiling on LTS kernels. In my case SUSE 15.5 has a kernel version of 5.14 but backports whatever broke this in the first place.

I'm not associated with Google or the maintainer of this repository, but I am hoping to maintain the contents of this repo for openSUSE!

I'm afraid to say, however, I don't think the maintainer of this GH repo should accept this PR, and you should consider closing it...

Those conditional checks are there because the changes to the dma-buf namespace that necessitated it weren't implemented until kernel 5.16. That conditional check must be there for general use and backwards compatibility etc. Upstream can't be held responsible for any issues introduced by third-party backports.

However, things like that are very much the job of hopeful maintainers. And in that capacity your issue and the associated fix are right on the money! 😁

So I've incorporated your patch into the package builds for Leap/SLES 15.5. 'Experimental' "hardware" repository. Hopefully that's okay with you? 🙂

I'm aiming to have this become part of the official openSUSE/SLES repositories very soon.

Thank you @chrBrd that all makes sense. I am going to close this PR in favor of a SUSE maintained version.

Your OBS setup for this is also a lot prettier than mine haha

This will be fixed by #16 (I think), just posting to notify everybody.
