From 542043e91df452ed09f382d8c41cdf3788f31b5e Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Mon, 24 May 2021 16:14:13 +0300 Subject: net: dsa: sja1105: parameterize the number of ports The sja1105 driver will gain support for the next-gen SJA1110 switch, which is very similar except for the fact it has more than 5 ports. So we need to replace the hardcoded SJA1105_NUM_PORTS in this driver with ds->num_ports. This patch is as mechanical as possible (save for the fact that ds->num_ports is not an integer constant expression). Signed-off-by: Vladimir Oltean Signed-off-by: David S.
