NTB: ntb_transport: fix debugfs_remove_recursive
The call to debugfs_remove_recursive(qp->debugfs_dir) of the sub-level directory must not be later than debugfs_remove_recursive(nt_debugfs_dir) of the top-level directory. Otherwise, the sub-level directory will not exist, and it would be invalid (panic) to attempt to remove it. This removes the top-level directory last, after sub-level directories have been cleaned up. Signed-off-by: Allen Hubbe <Allen.Hubbe@dell.com> Fixes: e26a5843f ("NTB: Split ntb_hw_intel and ntb_transport drivers") Signed-off-by: Jon Mason <jdmason@kudzu.us>
