From 49af6a7620c53b779572abfbfd7778e113154330 Mon Sep 17 00:00:00 2001 From: Colin Foster Date: Tue, 7 Dec 2021 09:00:28 -0800 Subject: [PATCH] net: dsa: ocelot: felix: Remove requirement for PCS in felix devices Existing felix devices all have an initialized pcs array. Future devices might not, so running a NULL check on the array before dereferencing it will allow those future drivers to not crash at this point Signed-off-by: Colin Foster Reviewed-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: Jakub Kicinski --- drivers/net/dsa/ocelot/felix.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/dsa/ocelot/felix.c b/drivers/net/dsa/ocelot/felix.c index 0e102caddb73..4ead3ebe947b 100644 --- a/drivers/net/dsa/ocelot/felix.c +++ b/drivers/net/dsa/ocelot/felix.c @@ -828,7 +828,7 @@ static void felix_phylink_mac_config(struct dsa_switch *ds, int port, struct felix *felix = ocelot_to_felix(ocelot); struct dsa_port *dp = dsa_to_port(ds, port); - if (felix->pcs[port]) + if (felix->pcs && felix->pcs[port]) phylink_set_pcs(dp->pl, &felix->pcs[port]->pcs); } -- 2.11.0
