The DWC2 driver should now be in good enough shape to move out of
staging. I have stress tested it overnight on RPI running mass
storage and Ethernet transfers in parallel, and for several days
on our proprietary PCI-based platform.

There are leaks of resources allocated by wlan_setup() and usb_dev refcnt
on failure paths in prism2sta_probe_usb().
The patch adds appropriate deallocations and removes invalid code
from hfa384x_corereset() failure handling.
unregister_wlandev() is wrong because it is not registered yet.
hfa384x_destroy() is just noop in init state.

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.

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.

`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:

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.
