Revision 9e28cfead2f8f5aba7df03c74c9ec645b5ffc5fd authored by Cai Huoqing on 28 September 2021, 13:48:49 UTC, committed by Jakub Kicinski on 29 September 2021, 00:28:54 UTC 
net: mdio-ipq4019: Fix the error for an optional regs resource
 
The second resource is optional which is only provided on the chipset
IPQ5018. But the blamed commit ignores that and if the resource is
not there it just fails.

the resource is used like this,
	if (priv->eth_ldo_rdy) {
		val = readl(priv->eth_ldo_rdy);
		val |= BIT(0);
		writel(val, priv->eth_ldo_rdy);
		fsleep(IPQ_PHY_SET_DELAY_US);
	}

This patch reverts that to still allow the second resource to be optional
because other SoC have the some MDIO controller and doesn't need to
second resource.
