From ea825e70d0e0798eda3a57b05c90f21f5a369128 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 18 Aug 2016 15:30:12 -0700 Subject: [PATCH] net: dsa: Export suspend/resume functions In preparation for allowing switch drivers to implement system-wide suspend/resume functions, export dsa_switch_suspend and dsa_switch_resume() such that these are callable from the appropriate driver specific suspend/resume functions.
