[PATCH 0/2] PCI: Fix potential double-free and add error logging

Posted by Jinhui Guo 3 months, 4 weeks ago

Hi all,

Two patches fix pci sysfs/procfs issues:

1. Avoid a double-free in pci_remove_resource_files() by clearing
   pdev->res_attr[i] and pdev->res_attr_wc[i] to NULL after kfree().
2. To make PCI bring-up failures easier to diagnose, log the errno
   returned by pci_create_sysfs_dev_files() and pci_proc_attach_device()
   in pci_bus_add_device().

Thanks,
Jinhui
