Subject: [PATCH 0/2] serial: 8250_dma: DMA Rx race fixes

Fix two races in DMA Rx completion and rearm handling.

I know in advance that the first patch will not be backport friendly
because of commit 56dc5074cbec ("serial: 8250_dma: Rearm DMA Rx if more
data is pending") that is not even in 6.1 but I can create the custom
backport on request.

Cc: stable@...r.kernel.org

  serial: 8250_dma: Fix DMA Rx rearm race
