Re: [PATCH 4/4] serial: 8250: Flush DMA Rx on RLSI

Returning true from handle_rx_dma() without flushing DMA first creates a data ordering hazard. If DMA Rx has handled any character at the point when RLSI occurs, the non-DMA path handles any pending characters jumping them ahead of those characters that are pending under DMA.

Maybe instead you can do --cc Guilles ... for entire series (and drop from other commit messages)?
