[ Upstream commit fd567ac20cb0377ff466d3337e6e9ac5d0cb15e4 ]
In commit 4f07b80c9733 ("tipc: check msg->req data len in tipc_nl_compat_bearer_disable") the same patch code was copied into routines: tipc_nl_compat_bearer_disable(), tipc_nl_compat_link_stat_dump() and tipc_nl_compat_link_reset_stats(). The two link routine occurrences should have been modified to check the maximum link name length and not bearer name length.
