Subject: [PATCH] net: stmmac: mark PM functions as __maybe_unused
Date: Mon, 13 Aug 2018 23:50:41 +0200 [thread overview]
Message-ID: <20180813215046.3663828-1-arnd@arndb.de> (raw)
The newly added suspend/resume functions cause a build warning
when CONFIG_PM is disabled:
drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:324:12: error: 'stmmac_pci_resume' defined but not used [-Werror=unused-function]
drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:306:12: error: 'stmmac_pci_suspend' defined but not used [-Werror=unused-function]
Mark them as __maybe_unused so gcc can drop them silently.
Fixes: b7d0f08e9129 ("net: stmmac: Fix WoL for PCI-based setups")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
