Wolfram Sang b28bdc9607 serial: sh-sci: protect invalidating RXDMA on shutdown ... [ Upstream commit aae20f6e34 ] The to-be-fixed commit removed locking when invalidating the DMA RX descriptors on shutdown. It overlooked that there is still a rx_timer running which may still access the protected data. So, re-add the locking.
