In ASYNC wait mode, next command kickoff can happen before previous command ISR execution is completed in below sequence: ASYNC command A -> triggered dsi_ctrl_isr for command A -> fired and executed atomic_set(&dsi_ctrl->dma_irq_trig, 1); wait_for_done for command A -> returns early as dsi_ctrl->dma_irq_trig is 1 ASYNC Command B -> triggered wait_for_done for command B -> waiting for cmd_dma_done dsi_ctrl_isr for command A -> executes complete_all(&dsi_ctrl->irq_info.cmd_dma_done); wait_for_done for command B -> returns success incorrectly based on complete_all of previous command isr and disable_status_interrupt() is not called. This leads to refcount of dma_done going wrong and dsi_ctrl_isr is not enabled on suspend resume. To fix this issue, mark command transfer successful only based on complete_all(cmd_dma_done). This way disable_status_interrupt() will be always called either from dsi_ctrl_isr or wait_for_done().
