staging: ozwpan: fix access byteorder for wMaxPacketSize in ozhcd.c
This patch fixes the access byteorder of wMaxPacketSize
which is __le16, following the USB standard, and needs to
be converted into native cpu byteorder in order to be accessed.
Instead of using le16_to_cpu(hep->desc.wMaxPacketSize),
it was used the usb_endpoint_maxp() function, defined in

comedi_device (*open) function in this driver then checks to
see if a usb device has been attached. If so the subdevice
information is updated based on the usb device and the comedi
device is then operational. If a usb device is not attached
the (*open) returns -ENODEV.
To simplify converting this driver to the comedi (*auto_attach)
mechanism, remove the attaching by serial number option.
Modify the usb (*probe) so that the first available slot is used.
If all the slots are used return -ENODEV.
Modify the comedi (*attach) so that the first unused slot that
has an attached usb device is used. If all the slots are used
return -ENODEV.
Since this ensures that the comedi device has an attached usb
device, remove the (*open) function and fully initialize the
subdevices during the (*attach).
Fix the comedi (*detach) so that the slot is made available
after detaching.

staging: comedi: dt9812: rename 'comedi' variable in struct slot_dt9812
Because of the usb (*probe) and comedi (*attach) disconnect, the struct
slot_dt9812 is used to pass the device data between the usb_driver and
the comedi_driver. The variable 'comedi' in this struct is used during
the comedi (*attach) to indicate if a slot is currently being used.
For aesthetic reasons, rename the variable to 'devpriv' since that is
what is actually saved in the pointer.
