Anders Roxell 4c7c36a7f3 serial: set suppress_bind_attrs flag only if builtin ... [ Upstream commit 646097940a ] When the test 'CONFIG_DEBUG_TEST_DRIVER_REMOVE=y' is enabled, arch_initcall(pl011_init) came before subsys_initcall(default_bdi_init). devtmpfs gets killed because we try to remove a file and decrement the wb reference count before the noop_backing_device_info gets initialized.
