From 8e5cb84c67e085ad4d8005dcecba3201f2b54504 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Wed, 30 Oct 2019 22:09:17 -0400 Subject: [PATCH] net: dsa: remove tree functions related to switches The DSA fabric setup code has been simplified a lot so get rid of the dsa_tree_remove_switch, dsa_tree_add_switch and dsa_switch_add helpers, and keep the code simple with only the dsa_switch_probe and dsa_switch_remove functions.
