3.14-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); } ... }
