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


From: Jingju Hou <houjingj@xxxxxxxxxxx>

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;
pdata = pxav3_get_mmc_pdata(dev);
