Vignesh Raghavendra 47e276e1c4 serial: 8250: 8250_omap: Terminate DMA before pushing data on RX timeout
[ Upstream commit 7cf4df30a9 ]

Terminate and flush DMA internal buffers, before pushing RX data to
higher layer. Otherwise, this will lead to data corruption, as driver
would end up pushing stale buffer data to higher layer while actual data
is still stuck inside DMA hardware and has yet not arrived at the
memory.
While at that, replace deprecated dmaengine_terminate_all() with
dmaengine_terminate_async().
