From fc0bc0190bc5ea1e44317c84c9f92f9196a7441b Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 19 Aug 2019 16:00:53 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: wrap SERDES IRQ in power function Now that mv88e6xxx_serdes_power is only called after driver setup, we can wrap the SERDES IRQ code directly within it for clarity.
