Subject: net: mscc: make sparse happy
X-Git-Tag: v4.18-rc3~40^2~8
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c2cd650b5b2bd6b57f2f62be65b1a8a576d4de6d;p=users%2Fjedix%2Flinux-maple.git

net: mscc: make sparse happy

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")
