#1205745 — [PATCH 3.16.y-ckt 113/118] mmc: sdhci-pxav3: fix platform_data is not initialized

3.16.7-ckt16 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jingju Hou <houjingj@marvell.com>

commit 9cd76049f0d90ae241f5ad80e311489824527000 upstream.

pdev->dev.platform_data is not initialized if match is true in function
sdhci_pxav3_probe. Just local variable pdata is assigned the return value
from function pxav3_get_mmc_pdata().

static int sdhci_pxav3_probe(struct platform_device *pdev) {

    struct sdhci_pxa_platdata *pdata = pdev->dev.platform_data;
    ...
    if (match) {
		ret = mmc_of_parse(host->mmc);
		if (ret)
			goto err_of_parse;
		sdhci_get_of_property(pdev);
		pdata = pxav3_get_mmc_pdata(dev);
     }
     ...
}
