The new SCMI clock protocol driver does not get probed that early in
boot. Brcmstb drivers typically have the following code when getting
a clock:
priv->clk = devm_clk_get(&pdev->dev, NULL);
if (IS_ERR(priv->clk)) {
dev_err(&pdev->dev, "Clock not found in Device Tree\n");
priv->clk = NULL;
}
This commit changes the driver to do what is below.
priv->clk = devm_clk_get(&pdev->dev, NULL);
if (IS_ERR(priv->clk)) {
if (PTR_ERR(priv->clk) == -EPROBE_DEFER)
return -EPROBE_DEFER;
dev_err(&pdev->dev, "Clock not found in Device Tree\n");
priv->clk = NULL;
}
