From: Joe Perches <joe@xxxxxxxxxxx> Subject: checkpatch: improve EXPORT_SYMBOL test for EXPORT_SYMBOL_NS uses The EXPORT_SYMBOL test expects a single argument but definitions of EXPORT_SYMBOL_NS have multiple arguments. Update the test to extract only the first argument from any EXPORT_SYMBOL related definition.
