Subject: tipc: remove unnecessary checking for node object
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=76d7882420d94075c806c074de241602a06e47e6;p=linux-beck.git

tipc: remove unnecessary checking for node object

tipc_node_create routine doesn't need to check whether a node
object specified with a node address exists or not because its
caller(ie, tipc_disc_recv_msg routine) has checked this before
calling it.
