Possible BUG REPORT against 5.0 USB Stack, file usb_audio.c, at line 767

In file Freescale_BM_USB_Stack_v5.0/Src/usb_core/device/sources/classes/audio/usb_audio.c, at line 767, you have (reformatted for readability):

error = audio_obj_ptr->class_specific_callback.callback((uint8_t)GET_CUR_COPY_PROTECT_CONTROL,

audio_obj_ptr->current_interface,

data,

size,

audio_obj_ptr->class_specific_callback.arg);

EVERY other call to the class_specific_callback that involves audio_obj_ptr->current_interface is of the form:

error = audio_obj_ptr->class_specific_callback.callback(audio_obj_ptr->current_interface,

cmd,

data,

size,

audio_obj_ptr->class_specific_callback.arg);

It appears to me that the call at line 767 is incorrect, and should instead be:

error = audio_obj_ptr->class_specific_callback.callback(audio_obj_ptr->current_interface,

(uint8_t)GET_CUR_COPY_PROTECT_CONTROL,

data,

size,

audio_obj_ptr->class_specific_callback.arg);
