Hartley Sweeten Convert the comedi_subdevice access from pointer math to array access.

Since the 'attach' callback is now optional it can be removed from the driver.

The second entry in the boardinfo is a dummy entry that would result in an unusable device. Remove the boardinfo fields and just use the open coded values in the subdevice setup.

This range is available as an exported symbol from the comedi core and "range_unipolar10". Use that instead of duplicating the range in this driver and remove the information from the boardinfo.

Since the driver does not require any external configuration options, disable the legacy attach by making the attach simply return -ENOSYS. This removes the need to walk the pci bus to find the pci_dev and the need for the pci_dev_put() in the detach.

This allows the comedi_pci_enable/disable helper functions to be shared instead of having an inline version in every comedi pci driver.

Change the return type from int to void All the detach functions, except for the comedi usb drivers, simply return success (0). Plus, the return code is never checked in the comedi core. The comedi usb drivers do return error codes but the conditions can never happen. The first check is: if (!dev) return -EFAULT; This checks that the passed comedi_device pointer is valid. The detach function itself is called using this pointer so it MUST always be valid or there is a bug in the core: if (dev->driver) dev->driver->detach(dev); And the second check: usb = dev->private; if (!usb) return -EFAULT; The dev->private pointer is setup in the attach function to point to the probed usb device. This value could be NULL if the attach fails. But, since the comedi core is going to unload the driver anyway and does not check for errors there is no gain by returning one. After removing these checks from the comedi usb drivers the detach functions required a bit of cleanup. 2. Remove all the printk noise in the detach functions All of the printk output is really just noise. The user did a rmmod to unload the driver, we really don't need to tell them about it. Also, some of the messages are output using: dev_dbg(dev->hw_dev, ... or dev_info(dev->hw_dev, ... Unfortunately the hw_dev value is only used by drivers that are doing DMA. For most drivers this variable is going to be NULL so the output is not going to work as expected. 3. Refactor a couple static 'free_resource' functions into the detach functions. The 'free_resource' function is only being called by the detach and it makes more sense to just absorb the code. 4. Remove a couple unnecessary braces for single statements. 5. Remove unnecessary comments. Most of the comedi drivers appear to be based on the comedi skel driver and have the comments from that driver included. These comments make sense in the skel driver for reference but they don't need to be in any of the actual drivers. 6. Remove all the extra whitespace. It's not needed to make the functions any more readable. 7. Remove the now unused 'attached_successfully' variable in the cb_pcimdda driver. This variable was only used to conditionally output some driver noise during the detach. Since all the printk's have been removed this variable is no longer necessary.

In the process, rename some of the symbols in the driver to standardize the comedi pci drivers. Based on the driver {name}: 1) Rename the comedi_driver to {name}_driver. 2) Use a static string {name} for the comedi_driver.driver_name. 3) Rename the pci probe/remove functions to {name)_pci_probe/remove. 4) Rename the pci id_table to {name}_pci_table. 5) Add the static string {name} for the pci_driver.name.

This is more typical of how other drivers are written and removes the need for the forward declarations.

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.
