+ *	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.
