Message-ID: <20131108100350.GS27977@elgon.mountain> (raw)

Hello Tony Prisk,

This is a semi-automatic email about new static checker warnings.

The patch 3a96dff0f828: "mmc: SD/MMC Host Controller for Wondermedia 
WM8505/WM8650" from Nov 18, 2012, leads to the following Smatch 
complaint:

drivers/mmc/host/wmt-sdmmc.c:764 wmt_mci_probe()
	 warn: variable dereferenced before check 'of_id' (see line 760)

drivers/mmc/host/wmt-sdmmc.c
   759			of_match_device(wmt_mci_dt_ids, &pdev->dev);
   760		const struct wmt_mci_caps *wmt_caps = of_id->data;
                                                      ^^^^^^^^^^^
Dereference.

   761		int ret;
   762		int regular_irq, dma_irq;
   763	
   764		if (!of_id || !of_id->data) {
                     ^^^^^
Check.

   765			dev_err(&pdev->dev, "Controller capabilities data missing\n");
   766			return -EFAULT;

regards,
dan carpenter
