Now, after being exposed for ten years to refactoring, general tree-wide changes and various janitor clean-up, it is really time to delete the driver for good. This was discovered as part of a checkpatch evaluation, investigating all reports of checkpatch's WARNING:OBSOLETE check. Signed-off-by: Lukas Bulwahn Acked-by: Luis Chamberlain --- Kalle, please pick this non-urgent driver clean-up patch.
