If anyone has any objections, please let me know. ------------------ From: Jingju Hou 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); } ... } Signed-off-by: Jingju Hou Fixes: b650352dd3df("mmc: sdhci-pxa: Add device tree support") Signed-off-by: Ulf Hansson Signed-off-by: Kamal Mostafa --- drivers/mmc/host/sdhci-pxav3.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mmc/host/sdhci-pxav3.c b/drivers/mmc/host/sdhci-pxav3.c index 9654246..b8f319d 100644 --- a/drivers/mmc/host/sdhci-pxav3.c +++ b/drivers/mmc/host/sdhci-pxav3.c @@ -257,6 +257,7 @@ static int sdhci_pxav3_probe(struct platform_device *pdev) goto err_of_parse; sdhci_get_of_property(pdev); pdata = pxav3_get_mmc_pdata(dev); + pdev->dev.platform_data = pdata; } else if (pdata) { /* on-chip device */ if (pdata->flags & PXA_FLAG_CARD_PERMANENT) -- 1.9.1
