[PATCH 5.3 084/135] net: stmmac: gmac4: bitrev32 returns u32
From: Greg Kroah-Hartman
Date: Tue Dec 03 2019 - 17:44:00 EST
From: Jose Abreu <Jose.Abreu@xxxxxxxxxxxx>
[ Upstream commit 4d7c47e34fab0d25790bb6e85b85e26fdf0090d5 ]
The bitrev32 function returns an u32 var, not an int. Fix it.
Fixes: 477286b53f55 ("stmmac: add GMAC4 core support")
