Hi Greg, Today's linux-next merge of the tty tree got a conflict in drivers/tty/serial/pch_uart.c between commit af6d17cdc8c8 ("pch_uart: Fix dma channel unallocated issue") from the tty.current tree and commit 44db113212d8 ("pch_uart: Delete unused structure member") from the tty tree. Just context changes. I fixed it up (see below) and can carry the fix as necessary. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc drivers/tty/serial/pch_uart.c index c2816f4,a5e6343..0000000 --- a/drivers/tty/serial/pch_uart.c +++ b/drivers/tty/serial/pch_uart.c @@@ -1447,11 -1455,8 +1455,10 @@@ static int pch_uart_verify_port(struct __func__); return -EOPNOTSUPP; #endif - priv->use_dma_flag = 1; - priv->use_dma = 1; dev_info(priv->port.dev, "PCH UART : Use DMA Mode\n"); + if (!priv->use_dma) + pch_request_dma(port); + priv->use_dma = 1; } return 0;
