Subject[PATCH 5.3 085/135] net: stmmac: xgmac: bitrev32 returns u32
Date
From: Jose Abreu <Jose.Abreu@synopsys.com>

[ Upstream commit 3d00e45d498fd5347cea653ef494c56731b651e0 ]

The bitrev32 function returns an u32 var, not an int. Fix it.

Fixes: 0efedbf11f07 ("net: stmmac: xgmac: Fix XGMAC selftests")
