  "message": "Subject: [PATCH 1/2] serial: Add flush_buffer() operation to uart_ops\n\nSerial drivers using DMA (like the atmel_serial driver) tend to get very\nconfused when the xmit buffer is flushed and nobody told them.  They\nalso tend to spew a lot of garbage since the DMA engine keeps running\nafter the buffer is flushed and possibly refilled with unrelated data.\n\nThis patch adds a new flush_buffer operation to the uart_ops struct,\nalong with a call to it from uart_flush_buffer() right after the xmit\nbuffer has been cleared. The driver can implement this in order to\nsyncronize its internal DMA state with the xmit buffer when the buffer\nis flushed.\n\nSigned-off-by: Haavard Skinnemoen \u003chaavard.skinnemoen@atmel.com\u003e\nAcked-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
