However, there's a patch for that already, on its way: https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/commit/?h=fixes-togreg&id=75183e461ce033605c3e85518a9f3d4e4ef848a3 Don't get discouraged, though, when fixing something that is not in our immediate area of interest! :-) Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
