could not be described before. In many cases, there's little value in
adding docs for these nested fields, and in cases like:

struct a {
struct b {
int c;
} d, e;

"c" would have to be described twice (as d.c and e.c) to make the warnings
go away.

We can no doubt do something smarter, but simply suppressing the warnings
for this case removes about 70 relatively useless warnings from the docs
build, freeing us to focus on the ones that matter more. So make
kerneldoc be silent about missing descriptions for any field containing a
