/**
* mod_firmware_load - load sound driver firmware
* @fn: filename
* @fp: return for the buffer.
*
* 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.
