I would prefer an enumeration instead; you can keep the documentation for those
status signals with kerneldoc on the new enum.

/**
  * enum core_ctx_status - Context decode status for core hardware
  * @CONTEXT_LIST_EMPTY:    No buffer queued on Core HW (must always be 0)
  * @CONTEXT_LIST_QUEUED:   Buffer queued to the core work list
  * @CONTEXT_LIST_DEC_DONE: Context decode done
  */
enum core_ctx_status {
	CONTEXT_LIST_EMPTY = 0,
	CONTEXT_LIST_QUEUED,
	CONTEXT_LIST_DEC_DONE,
}

Moreover, since this is a rather simple addition, please squash this commit with
patch [3/6] where you actually also introduce the actual usage of the new enum.

Cheers,
Angelo

Hi AngeloGioacchino,

Thanks for your suggestion.

Fixed in patch v2.
