+ * 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.
