Kconfig symbols with "prompt strings" should also have help text.

I expected checkpatch to catch that, but I tested it and there was no warning
from checkpatch about help text.  OTOH, there was a warning that there are
2 lines in this patch that end with whitespace, so that should be fixed.

Did you use checkpatch (scripts/checkpatch.pl)?
