IMHO the error is bogus.
This is the part of the patch:

diff --git a/linux-user/strace.c b/linux-user/strace.c
index de43238fa4..dc963accd5 100644
--- a/linux-user/strace.c

Maybe the warning is somewhat real, but *if* I should cut the line to
less than 80 chars, where should I break it?
E.g. like this?

+UNUSED static void print_encoded_string(abi_long addr, unsigned int maxlen,
+					 int last);
 UNUSED static void print_buf(abi_long addr, abi_long len, int last);
