Per Documentation/CodingStyle, better to put the whole thing onto one
line so that, say, "git grep 'attempting to unregister'" doesn't leave
one scratching ones head in confusion.

Of course, even better would be to get rid of the whole thing and
convert ARM to use SWIOTLB, but hey, one thing at a time ;)
