Al Cooper 6f2aa55b85 mmc: sdhci-brcmstb: Fix driver to defer on clk_get defer
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;
        }

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
