It was marked as BROKEN back in 2008. It is because the tty handling
in the driver is really broken.

There was some activity in January 2012 to fix the driver, but the
patch was commented to be bogus:
  https://lkml.org/lkml/2012/1/29/160
and we have not heard back from the author since then:
  https://lkml.org/lkml/2012/3/28/412

So since nobody stepped in and rewrote the driver, it is time to move
it out of line now. And drop it some time later if nobody comes up
with patches to fix the driver in staging.

commit 3a0db721

    "TTY: serial, move 68360 driver to staging"

did so because the driver had remained broken since 2008.  It also
added this text to the TODO file:

   "If no one steps up to adopt any of these drivers, they will
    be removed in the 3.4 release."

A quick search on the internet doesn't reveal anyone actively
trying to update/fix this driver, so follow through on the above
and remove it from the pending 3.4 release.

usbdux_attach_common() prints two messages via dev_info() that shows a
device has been attached.  The first of these messages includes an index
into a static array that the function determines by pointer subtraction,
assuming the pointer passed to the function points to an element of the
array.  Dan Carpenter pointed out that this was kind of ugly.  Since the
dev_info() that prints the array index doesn't add anything useful
(since no other messages print the array index and nothing else uses
it), let's just get rid of it.

comedi_auto_config() only needs to consider a single struct

which looks at all struct comedi_driver objects registered with the

The Comedi auto-configuration mechanism used to bind hardware devices to
comedi devices automatically is pretty kludgy.  It fakes a "manual"
configuration of the comedi device as though the COMEDI_DEVCONFIG ioctl
(or the 'comedi_config' utility) were used.  In particular, the
low-level comedi driver's '->attach()' routine is called with a pointer
to the struct comedi_device being attached and a pointer to a 'struct
devconfig' containing a device name string and a few integer options to
help the attach routine locate the device being attached.  In the case
of PCI devices, these integer options are the PCI bus and slot numbers.
In the case of USB devices, there are no integer options and it relies
more on pot luck to attach the correct device.

This patch adds a couple of bus-type-specific attach routine hooks to
the struct comedi_driver, which a low-level driver can optionally fill
in if it supports auto-configuration.

A low-level driver that supports auto-configuration of {PCI,USB} devices
calls the existing comedi_{pci,usb}_auto_config() when it wishes to
auto-configure a freshly probed device (maybe after loading firmware).
This will call the new '->attach_{pci,usb}()' hook if the driver has
defined it, otherwise it will fall back to calling the '->attach()' hook
as before.  The '->attach_{pci,usb}()' hook gets a pointer to the struct
comedi_device and a pointer to the struct {pci_dev,usb_interface} and
can figure out the {PCI,USB} device details for itself.

comedi_auto_config() associates a Comedi minor device number with an
auto-configured hardware device and comedi_auto_unconfig() disassociates
it.  Currently, these use the hardware device's private data pointer to
point to some allocated storage holding the minor device number.  This
is a bit of a waste of the hardware device's private data pointer,
preventing it from being used for something more useful by the low-level
comedi device drivers.  For example, it would make more sense if
comedi_usb_auto_config() was passed a pointer to the struct
usb_interface instead of the struct usb_device, but this cannot be done
currently because the low-level comedi drivers already use the private
data pointer in the struct usb_interface for something more useful.

This patch stops the comedi core hijacking the hardware device's private
data pointer.  Instead, comedi_auto_config() stores a pointer to the
hardware device's struct device in the struct comedi_device_file_info
associated with the minor device number, and comedi_auto_unconfig()
calls new function comedi_find_board_minor() to recover the minor device
number associated with the hardware device.

The comedi_pci_auto_config() and comedi_usb_auto_config() functions
currently take a board name parameter which is actually a driver name
parameter.  Replace it with a pointer to the struct comedi_driver.  This
will allow comedi_pci_auto_config() and comedi_usb_auto_config() to call
bus-type-specific auto-configuration hooks in the struct comedi_driver
if they exist (they don't yet).  The idea is that these
bus-type-specific auto-configuration hooks won't have to search the bus
for the device being auto-configured like 'attach()' hook has to.
