There is something strange in your question. You have MODE=context but
you show the output for MODE=patch. The rule dcf matches a call to
debugfs_create_file, and the context rule matching DEFINE_SIMPLE_ATTRIBUTE
is only activated if dcf succeeds. So when the context rule gives a
report, there is always a corresponding call to debugfs_create_file in the
same file, it is just not highlighted. So the request is that it should
be highlighted as well?
