From 000ba1f2ebf0d6f93b9ae6cfbe5417e66f1b8e8c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 27 Apr 2017 21:09:52 +0200 Subject: igb: mark PM functions as __maybe_unused The new wake function is only used by the suspend/resume handlers that are defined in inside of an #ifdef, which can cause this harmless warning: drivers/net/ethernet/intel/igb/igb_main.c:7988:13: warning: 'igb_deliver_wake_packet' defined but not used [-Wunused-function] Removing the #ifdef, instead using a __maybe_unused annotation simplifies the code and avoids the warning.
