Since commitcdd30ebb1b
("module: Convert symbol namespace to string literal"), when MODULE_IMPORT_NS() is missing, 'make nsdeps' inserts pointless code: MODULE_IMPORT_NS("ns"); Here, "ns" is not a namespace, but the variable in the semantic patch. It must not be quoted. Instead, a string literal must be passed to Coccinelle. Fixes:cdd30ebb1b
