- * 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.
