From mboxrd@z Thu Jan 1 00:00:00 1970 From: Antoine Tenart Subject: [PATCH net] net: mscc: make sparse happy Date: Fri, 22 Jun 2018 11:50:52 +0200 Message-ID: <20180622095052.26726-1-antoine.tenart@bootlin.com> Cc: Antoine Tenart , f.fainelli@gmail.com, andrew@lunn.ch, netdev@vger.kernel.org, linux-kernel@vger.kernel.org, thomas.petazzoni@bootlin.com, alexandre.belloni@bootlin.com, quentin.schulz@bootlin.com, allan.nielsen@microsemi.com To: davem@davemloft.net Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org This patch fixes a sparse warning about using an incorrect type in argument 2 of ocelot_write_rix(), as an u32 was expected but a __be32 was given. The conversion to u32 is forced, which is safe as the value will be written as-is in the hardware without any modification.
