[PATCH 5.3 123/140] net: dsa: fix switch tree list

From: Greg Kroah-Hartman
Date: Fri Nov 08 2019 - 14:11:23 EST


From: Vivien Didelot <vivien.didelot@xxxxxxxxx>

[ Upstream commit 50c7d2ba9de20f60a2d527ad6928209ef67e4cdd ]

If there are multiple switch trees on the device, only the last one
will be listed, because the arguments of list_add_tail are swapped.

Fixes: 83c0afaec7b7 ("net: dsa: Add new binding implementation")
