Similar fix is already in Linus' master tree, see
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4e5d56bdf892e18832a6540b63ebf709966bce2a

Also note:
 [1] That commit from Linux tree won't apply cleanly on U-Boot
     due to a bit different context.
 [2] Even if manually tweaked it looks like it is incomplete:
     ------------------->8-------------------
     )\(.*\).*\s{ <-- HERE /@scripts/checkpatch.pl line 2828.
     ------------------->8-------------------

So with above in mind could you please apply that patch posted by
Moritz?

This fixes checkpatch in Fedora 23 - in current state it is way too noisy.
