From f0fd1787a0db7b23ec859e50af3b66d9e8cc8c56 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5/6] net: dsa: mv88e6xxx: Fix off by in one in
mv88e6185_phylink_get_caps()
The <= ARRAY_SIZE() needs to be < ARRAY_SIZE() to prevent an out of
bounds error.
Fixes: d4ebf12bcec4 ("net: dsa: mv88e6xxx: populate supported_interfaces and mac_capabilities")
