scripts/cocci: add Zephyr macro file (15ed5865) · Commits · Wenxi XU / zephyr

Zephyr uses some defines to provide additional information about the item being declared. When unrecognized these can confuse the Coccinelle parser so that it does not apply semantic patches in situations where they should be applied. Add a macro file that extends the Coccinelle builtin macro file with some identifiers that are specific to Zephyr. Signed-off-by:
