- * usb_decode_ctrl - Returns human readable representation of control request.
- * @str: buffer to return a human-readable representation of control request.
- *       This buffer should have about 200 bytes.
- * @size: size of str buffer.
- * @bRequestType: matches the USB bmRequestType field
- * @bRequest: matches the USB bRequest field
- * @wValue: matches the USB wValue field (CPU byte order)
- * @wIndex: matches the USB wIndex field (CPU byte order)
- * @wLength: matches the USB wLength field (CPU byte order)
- *
- * Function returns decoded, formatted and human-readable description of
- * control request packet.
- *
- * The usage scenario for this is for tracepoints, so function as a return
- * use the same value as in parameters. This approach allows to use this
- * function in TP_printk
- *
- * Important: wValue, wIndex, wLength parameters before invoking this function
- * should be processed by le16_to_cpu macro.
