* Load the firmware for a sound module (up to 128K) into a buffer.
|

* The buffer is returned in *fp. It is allocated with vmalloc so is

|
|
* virtually linear and not DMAable. The caller should free it with
|

|
|
* vfree when finished.

* The length of the buffer is returned on a successful load, the

|
|
* value zero on a failure.
|

|
|
*
|
||
|
|
* Caution: This API is not recommended. Firmware should be loaded via
|
||
|
|
* request_firmware.
