The postconfig for drivers that support async commands currently can

Change the BUG_ON so that a dev_warn() is output and the postconfig
returns -EINVAL. This will prevent the comedi core from attaching to
the faulty driver but does not BUG the kernel.

Factor the setup of an async subdevice out of postconfig(). This allows
bringing the code back a couple indents and makes the postconfig a bit

Bernd Porr reports success getting comedi to work on ARM.  He writes:

"""
comedi works nicely on the Raspberry PI. I've compiled the rpi kernel
with comedi enabled and it works with the USBDUX-sigma (need to test the
other boards). With comedirecord running I can plot one channel at 1kHz
without buffer overflow (resulting to 70% load).

So, I guess we just need to add "ARM" to Kconfig in the comedi subdir?

         depends on BROKEN || FRV || M32R || MN10300 || SUPERH || TILE || X86 || ARM

I'm running just now 3.2.27 but also the development kernel compiles
with ARM enabled (haven't tested yet).

The CONFIG_LINE6_USB_DUMP_PCM config option prints a hexdump of PCM
audio data as URBs are sent and received.  The usbmon feature should be
used instead of manually dumping PCM URBs.  There are a few advantages
to using usbmon:

 * Can be turned on/off at runtime
 * Provides full USB-level traffic
 * tcpdump and wireshark support for powerful analysis
 * No driver-specific code is required

This is the last user of line6_write_hexdump() so we drop it too.
