If pci_ioremap_bar() fails during probe, we "goto release;" and free the host, but then we return 0 -- which tells sdhci_pci_probe() that the probe succeeded. Since we think the probe succeeded, when we unload sdhci we'll go to sdhci_pci_remove_slot() and it will try to dereference slot->host, which is now NULL because we freed it in the error path earlier. The patch simply sets ret appropriately, so that sdhci_pci_probe() will detect the failure immediately and bail out. Signed-off-by: Chris Ball <cjb@laptop.org> Cc: <stable@kernel.org> |
