When moving over to the new sw_ring_preenable I managed to add this callback to only one of the two iio_info structures. As such only some devices will currently work. Signed-off-by:

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.

For now just implementing the exporting APIs, not yet importing. And kmap is rejected on tiled buffers (although the usefulness of that seems questionable, but could be added later if needed). Signed-off-by:

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. Signed-off-by:

comedi_auto_config() only needs to consider a single struct comedi_driver object, but it currently calls comedi_device_attach() which looks at all struct comedi_driver objects registered with the Comedi core. Instead, call the recently added comedi_auto_config_helper() with a new wrapper comedi_auto_config_wrapper() to mimic the effect of comedi_device_attach() for a single struct comedi_driver.

Pass a pointer to the struct comedi_driver to comedi_auto_config() instead of the driver name. comedi_auto_config() will be changed to make use of this. It currently calls comedi_device_attach() which examines the whole list of struct comedi_driver objects. It will be changed to restrict itself to just the supplied struct comedi_driver object.

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.

Split the post-config part of comedi_device_attach() into new function comedi_device_postconfig() and rearrange the rest of the function a bit. The new comedi_device_postconfig() function will be called by some new bus-type-specific auto-attach functions. Signed-off-by:

The comedi_usb_auto_config() and comedi_usb_auto_unconfig() functions currently take a 'struct usb_device *'. It makes more sense to pass a 'struct usb_interface *' to allow for composite USB devices. Signed-off-by:

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. Signed-off-by:

The das08 driver supports both ISA and PCI cards, but currently is configured outside the ISA and PCI comedi driver sections. The module is also used by the das08_cs driver. This patch splits the configuration to make the ISA and PCI parts separately selectable, and changes the driver to only include the selected ISA and/or PCI board types. Also, if neither the ISA or PCI parts are selected, and the module is only needed for the das08_cs driver, don't register the driver as a comedi driver as it doesn't have any boards to support.

The DMA functionality fails to work on little endian processors, such as found on x86 based platforms. The DMA engine copies the link list descriptors from memory into big endian registers. On little endian systems this results in the values being byte swapped. This patch uses standard kernel functionality to ensure that the descriptors are stored in big endian format. Signed-off-by:

Inside the array we check ms_start_idx[seg_no + 1] so on the last round through we end up going past the end of the array. Also if we don't break out of the loop early then we are beyond the end of the array there as well. With this change, if we don't find what we are looking for, we end on the last element of the array. Signed-off-by:
