Subject: [PATCH v3] mmc: sdhci-pxav3: fix platform_data is not initialized
Date: Fri, 24 Jul 2015 09:15:45 +0800 [thread overview]
Message-ID: <1437700545-14660-1-git-send-email-houjingj@marvell.com> (raw)
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);
}
...
}
