Reason why this change is needed

In lib_rend/lib_rend.c function renderIsmToMasa the variable

float tmpRendBuffer[MAX_NUM_OBJECTS][L_FRAME48k];

is used as the input argument to

• copyBufferTo2dArray expecting the argument to be float array[MAX_OUTPUT_CHANNELS][L_FRAME48k], and
• accumulate2dArrayToBuffer expecting the argument to be float array[MAX_OUTPUT_CHANNELS][L_FRAME48k].

In both cases, the actual number of channels to process is read from buffer->config.numChannels and no over-indexing takes place.

Description of the change

Change the function interface definitions to use undefined first dimension size for the 2D inputs:

• copyBufferTo2dArray to use float array[][L_FRAME48k]
• accumulate2dArrayToBuffer to use float array[][L_FRAME48k]

Affected operating points

• Potentially all external renderer rendering operations
• Since the change is only in the definition of the function interface, everything should be BE.
