Just checking for ifdefs cause build issues as reported by
kernel test:

So, use IS_ENABLED() instead.  

Hi,

I would like to test this (the change doesn't make much sense to me),
but I cannot find the kernel config file nor the kernel test robot's
email of this report.

Please include an lkml.kernel.org/r/<message_id> reference to such emails
so that interested parties can join the party.

The message was not c/c to lkml. You can see the original here:

https://www.mail-archive.com/linux-media@vger.kernel.org/msg130809.html

Does this patch apply only to your media tree?  so hopefully I can see it in
linux-next on Monday.

Yes, as it is over another two patches applied there.

If you want to test it earlier, it is in the top of the master branch:

Thanks.

The patch doesn't make any sense to me.  I would like to see an
explanation of why this is needed, other than "it fixes the build." ;)

But it does fix the build, so:
