Yuan Can 98af0a33c1 NTB: amd: Fix error handling in amd_ntb_pci_driver_init() ... A problem about ntb_hw_amd create debugfs failed is triggered with the following log given: [ 618.431232] AMD(R) PCI-E Non-Transparent Bridge Driver 1.0 [ 618.433284] debugfs: Directory 'ntb_hw_amd' with parent '/' already present! The reason is that amd_ntb_pci_driver_init() returns pci_register_driver() directly without checking its return value, if pci_register_driver() failed, it returns without destroy the newly created debugfs, resulting the debugfs of ntb_hw_amd can never be created later. amd_ntb_pci_driver_init() debugfs_create_dir() # create debugfs directory pci_register_driver() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without destroy debugfs directory Fix by removing debugfs when pci_register_driver() returns error.
