net: stmmac: dwmac-sun8i: use return val of readl_poll_timeout()
When readl_poll_timeout() timeout, we'd better directly use its return value. Before this patch: [ 2.145528] dwmac-sun8i: probe of 4500000.ethernet failed with error -14 After this patch: [ 2.138520] dwmac-sun8i: probe of 4500000.ethernet failed with error -110 Signed-off-by: Jisheng Zhang <jszhang@kernel.org> Acked-by: Jernej Skrabec <jernej.skrabec@gmail.com> Signed-off-by: David S.
