This uses a new `auto_attach()` hook in the `struct comedi_driver`. This new hook will eventually replace the bus-specific `attach_pci()` and `attach_usb()` hooks in the low-level comedi drivers. When the `auto_attach()` hook is called in the low-level driver, the `hw_dev` member of the `struct comedi_device` will have already been set to the hardware device passed to `comedi_auto_config()`. The low-level driver can convert this to some bus-device wrapper structure pointer, possibly with the help of the `context` parameter that is passed unchanged from the `comedi_auto_config()` call. Also export the existing `comedi_auto_unconfig()` function as the matching call to `comedi_auto_config()`. Signed-off-by: Ian Abbott Signed-off-by: Greg Kroah-Hartman --- Reading git-diff-tree failed
