Subject: tipc: Update "previous node" indicators when node address changes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6d4a6672c8263f98544d2b91690dc7074b144090;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

tipc: Update "previous node" indicators when node address changes

This patch ensures that the "previous node" field in any existing
TIPC port message header templates is updated properly when a TIPC
network address is assigned to the node.  (Previously, only the
"originating node" field was updated.)
