Functions for reading DSP code to load into DSP
hpi_dspcode_defines HPI DSP code loading method
Define exactly one of these to select how the DSP code is supplied to
the adapter.
End users writing applications that use the HPI interface do not have to
use any of the below defines; they are only necessary for building drivers
HPI_DSPCODE_FILE:
DSP code is supplied as a file that is opened and read from by the driver.
HPI_DSPCODE_FIRMWARE:
DSP code is read using the hotplug firmware loader module.
Only valid when compiling the HPI kernel driver under Linux.

* 2.4.22 usb-uhci seems buggy for async unlinking and results in
* oops. in such a cse, pass async_unlink=0 option.
* - the linked URBs would be preferred but not used so far because of
* the instability of unlinking.
* - type II is not supported properly. there is no device which supports
* this type *correctly*. SB extigy looks as if it supports, but it's
* indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).
