coccicheck: add support for DEBUG_FILE
Enable to capture stderr via a DEBUG_FILE variable passed to coccicheck. You can now do: $ rm -f cocci.err $ export COCCI=scripts/coccinelle/free/kfree.cocci $ make coccicheck MODE=report DEBUG_FILE=cocci.err ... $ cat cocci.err This will be come more useful once we add support to use more things which would go into stderr, such as profiling. That will be done separately in another commit. Expand Documentation/coccinelle.txt with details. Signed-off-by: Luis R.
