Subject: [PATCH net] net: mscc: make sparse happy
Date: Fri, 22 Jun 2018 11:50:52 +0200	[thread overview]
Message-ID: <20180622095052.26726-1-antoine.tenart@bootlin.com> (raw)

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.

Fixes: 08d02364b12f ("net: mscc: fix the injection header")
Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com>
