The problem is that we dereference "privdata->pci_dev" when we print the error messages in amd_mp2_pci_init(): dev_err(ndev_dev(privdata), "Failed to enable MP2 PCI device\n"); ^^^^^^^^^^^^^^^^^ Fixes: 529766e0a011 ("i2c: Add drivers for the AMD PCIe MP2 I2C controller") Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Signed-off-by: Wolfram Sang <wsa@xxxxxxxxxxxxx> Cc: stable@xxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> diff --git a/drivers/i2c/busses/i2c-amd-mp2-pci.c b/drivers/i2c/busses/i2c-amd-mp2-pci.c index 5e4800d72e00b..cd3fd5ee5f65d 100644 --- a/drivers/i2c/busses/i2c-amd-mp2-pci.c +++ b/drivers/i2c/busses/i2c-amd-mp2-pci.c @@ -349,12 +349,12 @@ static int amd_mp2_pci_probe(struct pci_dev *pci_dev, if (!privdata) return -ENOMEM; + privdata->pci_dev = pci_dev; rc = amd_mp2_pci_init(privdata, pci_dev); if (rc) return rc; mutex_init(&privdata->c2p_lock); - privdata->pci_dev = pci_dev; pm_runtime_set_autosuspend_delay(&pci_dev->dev, 1000); pm_runtime_use_autosuspend(&pci_dev->dev);
