Re: [Sound-open-firmware] [PATCH v14 2/2] mailbox: mediatek: add support for adsp mailbox controller

+static struct mtk_adsp_mbox_priv *get_mtk_adsp_mbox_priv(struct mbox_controller *mbox) +{

•   return container_of(mbox, struct mtk_adsp_mbox_priv, mbox);
  

+}

this could probably be inline

+static struct mbox_chan *mtk_adsp_mbox_xlate(struct mbox_controller *mbox,

•                                        const struct of_phandle_args *sp)
  

+{

•   return mbox->chans;
  

+}

also could probably benefit from inline
