Subject: net/dccp: dccp_bad_service_code can be boolean
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=45ae74f56162e7a017c3a4e130cf1bcd8d2d17cc;p=openwrt%2Fstaging%2Fblogic.git

net/dccp: dccp_bad_service_code can be boolean

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.
