From 198b34783ab10d0c58bf2ae2574e7fc704129058 Mon Sep 17 00:00:00 2001 From: Arun Ramadoss Date: Tue, 17 May 2022 15:13:29 +0530 Subject: [PATCH] net: dsa: microchip: move port memory allocation to ksz_common ksz8795 and ksz9477 init function initializes the memory to dev->ports, mib counters and assigns the ds real number of ports. Since both the routines are same, moved the allocation of port memory to ksz_switch_register after init. Signed-off-by: Arun Ramadoss Signed-off-by: David S.
