Subject: igb: mark PM functions as __maybe_unused
Patch-mainline: v4.13-rc1
Git-commit: 000ba1f2ebf0d6f93b9ae6cfbe5417e66f1b8e8c
References: bsc#1056651 FATE#322191 bsc#1056643 FATE#322192
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.
Fixes: b90fa8763560 ("igb: Enable reading of wake up packet")
