Since recently we have kernel_read_file_from_path(), and it's doing the same thing as our own home-baked mod_firmware_load(). Let's use the official API function and clean up the old code. Signed-off-by: Takashi Iwai <tiwai@suse.de>

/**
|
|
* 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.
