net: ionic: Fix error handling in ionic_init_module()
A problem about ionic create debugfs failed is triggered with the following log given: [ 415.799514] debugfs: Directory 'ionic' with parent '/' already present! The reason is that ionic_init_module() returns ionic_bus_register_driver() directly without checking its return value, if ionic_bus_register_driver() failed, it returns without destroy the newly created debugfs, resulting the debugfs of ionic can never be created later. ionic_init_module() ionic_debugfs_create() # create debugfs directory ionic_bus_register_driver() pci_register_driver() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without destroy debugfs directory Fix by removing debugfs when ionic_bus_register_driver() returns error.
