Remove "Control of internal reference" from the list of unimplemented features, since as of commit a405b00e , external reference is supported if the device has a regulator and falls back to internal if it doesn't. While we are modifying the header, let's make it more concise and remove a redundant filename. Signed-off-by:

Add support to the dummy driver for basic carveout and chunk heaps. Since we're generating these heaps at module_init, and we want this driver to be generic enough to be tested on any arch, we don't have the ability to alloc bootmem, so both of these heaps are conventionally allocated using alloc_pages(), which limits us to 4M in size. Should look into using CMA for heap allocation eventually, but this provides enough to test the basic functionality of the heaps.

Comedi core now reports that a device has been attached so that the driver itself won't need to do it any longer. The driver now just outputs the offset of the ADC converter which is a soft indicator of the health of the board and also the user can grep this value from the kernel log easier for debugging purposes.

The function usbduxsigma_getstatusinfo() returns a negative value in case there has been a communication error with the board. This should always work and if this communication fails then there is something seriously wrong with the board. This is now returned to the caller so that it can terminte the auto attachement. The return command also prevents printing out the offset value in case of a fault. Signed-off-by:

Added success message to the driver autoconfig and error message in case it fails. A success message is required so that the user can find out which comedi driver has been associated with which udev device. This also makes troubleshooting much easier when more than one card is in the computer or there is a mix of USB and PCI devices. As Ian suggested we should report both the driver and the board which might have different names, especially if one driver covers a range of different boards. Signed-off-by:

`comedi_free_board_dev()` is called (via `comedi_auto_unconfig()` --> `comedi_release_hardware_device()`) when an auto-configured comedi device is removed. This destroys the main sysfs class device and then calls `comedi_device_cleanup()` to clean up the comedi device. For comedi devices that have comedi subdevices that asynchronous commands, the clean up involves destroying the sysfs class devices associated with those subdevices. There is a bug in the above sequence because the sysfs class devices associated with the comedi subdevices are children of the sysfs class device associated with the main comedi device. Therefore they will have been automatically destroyed when the main sysfs class device is destroyed. When they are destroyed again as part of the clean-up, they will not be found, leading to a warning and a stack trace similar to this: ------------[ cut here ]------------ WARNING: CPU: 1 PID: 1213 at fs/sysfs/group.c:214 sysfs_remove_group+0x4e/0xa7() sysfs group ffffffff817504c0 not found for kobject 'comedi4_subd0' Modules linked in: nfsd auth_rpcgss oid_registry exportfs nfs_acl lockd bridge stp llc sunrpc fuse binfmt_misc cpufreq_userspace sr_mod snd_hda_codec_analog cdrom powernow_k8 kvm_amd kvm amplc_pci230(C) 8255(C) comedi(C) pcmcia xhci_hcd ehci_pci pcmcia_core ohci_pci ohci_hcd ehci_hcd usbcore snd_hda_intel snd_hda_codec snd_pcm k8temp snd_page_alloc 8139too snd_timer snd soundcore mii usb_common forcedeth pata_amd CPU: 1 PID: 1213 Comm: kworker/u4:6 Tainted: G C 3.13.0-rc5-ija1+ #20 Hardware name: System manufacturer System Product Name/M2N-E, BIOS ASUS M2N-E ACPI BIOS Revision 5001 03/23/2010 Workqueue: sysfsd sysfs_schedule_callback_work 0000000000000000 ffff8800bf17fb38 ffffffff814672ce ffff8800bf17fb80 ffff8800bf17fb70 ffffffff8103470b ffffffff8114f780 0000000000000000 ffffffff817504c0 ffff8800bf39f410 ffff880139b68670 ffff8800bf17fbd0 Call Trace: [<ffffffff814672ce>] dump_stack+0x45/0x56 [<ffffffff8103470b>] warn_slowpath_common+0x7a/0x93 [<ffffffff8114f780>] ? sysfs_remove_group+0x4e/0xa7 [<ffffffff8103476b>] warn_slowpath_fmt+0x47/0x49 [<ffffffff8114e92d>] ? sysfs_get_dirent_ns+0x5e/0x66 [<ffffffff8114f780>] sysfs_remove_group+0x4e/0xa7 [<ffffffff8132aac0>] dpm_sysfs_remove+0x37/0x3b [<ffffffff81323781>] device_del+0x3e/0x173 [<ffffffff813238c3>] device_unregister+0xd/0x18 [<ffffffff8132392e>] device_destroy+0x33/0x37 [<ffffffffa0212086>] comedi_free_subdevice_minor+0x80/0x92 [comedi] [<ffffffffa02128bb>] comedi_device_detach+0x79/0x152 [comedi] [<ffffffffa020f223>] comedi_device_cleanup+0x36/0x57 [comedi] [<ffffffffa020f275>] comedi_free_board_dev+0x31/0x3c [comedi] [<ffffffffa0211f2a>] comedi_release_hardware_device+0x5a/0x73 [comedi] [<ffffffffa0212547>] comedi_auto_unconfig+0xe/0x10 [comedi] [<ffffffffa021357c>] comedi_pci_auto_unconfig+0x10/0x12 [comedi] [<ffffffff811d2335>] pci_device_remove+0x40/0x8a [<ffffffff813261d0>] __device_release_driver+0x84/0xda [<ffffffff81326244>] device_release_driver+0x1e/0x2b [<ffffffff811cdcb5>] pci_stop_bus_device+0x44/0x87 [<ffffffff811cdde2>] pci_stop_and_remove_bus_device+0xd/0x18 [<ffffffff811d3f3d>] remove_callback+0x20/0x2f [<ffffffff8114d1f7>] sysfs_schedule_callback_work+0xf/0x70 [<ffffffff81049498>] process_one_work+0x1d6/0x34c [<ffffffff81049a5f>] worker_thread+0x1cf/0x2b5 [<ffffffff81049890>] ? rescuer_thread+0x258/0x258 [<ffffffff8104e0e6>] kthread+0xd6/0xde [<ffffffff8104e010>] ? kthread_create_on_node+0x160/0x160 [<ffffffff81472cbc>] ret_from_fork+0x7c/0xb0 [<ffffffff8104e010>] ? kthread_create_on_node+0x160/0x160 ---[ end trace 94722aa2936a7adf ]--- To correct the bug, rearrange `comedi_free_board_dev()` to destroy the main sysfs class device *after* the clean-up operation.

sleep_on and related functions are going away and should not be used in this driver any more. This removes the call to interruptible_sleep_on for a wait queue that is never woken up, and replaces an interruptible_sleep_on_timeout call with the equivalent wait_event_interruptible_timeout() to avoid a small race. Both call sites still look fishy and need more work.
