scripts: Coccinelle script for namespace dependencies. A script that uses the '<module>.ns_deps' files generated by modpost to automatically add the required symbol namespace dependencies to each module. Usage: 1) Move some symbols to a namespace with EXPORT_SYMBOL_NS() or define DEFAULT_SYMBOL_NAMESPACE 2) Run 'make' (or 'make modules') and get warnings about modules not importing that namespace. 3) Run 'make nsdeps' to automatically add required import statements to said modules. This makes it easer for subsystem maintainers to introduce and maintain symbol namespaces into their codebase.

scripts: add_namespace: Fix coccicheck failed Now all scripts in scripts/coccinelle to be automatically called by coccicheck. However new adding add_namespace.cocci does not support report mode, which make coccicheck failed. This add "virtual report" to make the coccicheck go ahead smoothly.
