Subject: [PATCH] [net-next] mtk-star-emac: mark PM functions as __maybe_unused
Date: Wed, 27 May 2020 15:34:45 +0200	[thread overview]
Message-ID: <20200527133513.579367-1-arnd@arndb.de> (raw)

Without CONFIG_PM, the compiler warns about two unused functions:

drivers/net/ethernet/mediatek/mtk_star_emac.c:1472:12: error: unused function 'mtk_star_suspend' [-Werror,-Wunused-function]
drivers/net/ethernet/mediatek/mtk_star_emac.c:1488:12: error: unused function 'mtk_star_resume' [-Werror,-Wunused-function]

Mark these as __maybe_unused.

Fixes: 8c7bd5a454ff ("net: ethernet: mtk-star-emac: new driver")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
