From 274cdb46e98b965449c68d912bcc45899ba34593 Mon Sep 17 00:00:00 2001 From: Egil Hjelmeland Date: Tue, 8 Aug 2017 00:22:21 +0200 Subject: net: dsa: lan9303: Only allocate 3 ports Save 2628 bytes on arm eabi by allocate only the required 3 ports. Now that ds->num_ports is correct: In net/dsa/tag_lan9303.c eliminate duplicate LAN9303_MAX_PORTS, use ds->num_ports. (Matching the pattern of other net/dsa/tag_xxx.c files.)
