From 880e6269fd6e60249c8f5f1b98295e9f7e56636d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 27 May 2020 15:47:00 +0200 Subject: [PATCH] e1000e: fix unused-function warning The CONFIG_PM_SLEEP #ifdef checks in this file are inconsistent, leading to a warning about sometimes unused function: drivers/net/ethernet/intel/e1000e/netdev.c:137:13: error: unused function 'e1000e_check_me' [-Werror,-Wunused-function] Rather than adding more #ifdefs, just remove them completely and mark the PM functions as __maybe_unused to let the compiler work it out on it own.
