Message-Id: <20160314.130645.572195280477206552.davem@davemloft.net> Date: Mon, 14 Mar 2016 13:06:45 -0400 (EDT) From: David Miller <davem@...emloft.net> To: arnd@...db.de Cc: nbd@...nwrt.org, blogic@...nwrt.org, matthias.bgg@...il.com, netdev@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-mediatek@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: Re: [PATCH 3/3] net: mediatek: check device_reset return code From: Arnd Bergmann <arnd@...db.de> Date: Mon, 14 Mar 2016 15:07:12 +0100 > The device_reset() function may fail, so we have to check > its return value, e.g. to make deferred probing work correctly. > gcc warns about it because of the warn_unused_result attribute: > > drivers/net/ethernet/mediatek/mtk_eth_soc.c: In function 'mtk_probe': > drivers/net/ethernet/mediatek/mtk_eth_soc.c:1679:2: error: ignoring return value of 'device_reset', declared with attribute warn_unused_result [-Werror=unused-result] > > This adds the trivial error check to propagate the return value > to the generic platform device probe code. > > Signed-off-by: Arnd Bergmann <arnd@...db.de> Applied.
