[PATCH 6/9] net/dccp: dccp_bad_service_code can be boolean

Show all headers | View raw

This patch makes dccp_bad_service_code return bool due to these
particular functions only using either one or zero as their return
value.

dccp_list_has_service is also been made return bool in this patchset.

No functional change.
