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

[Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx>]

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.
