Hi,
These four fixes are pretty important for our atmel_serial driver as they
deal with closing/re-opening of ports. They fix race condition and
null pointers dereference.
I added the stable tag to each of them (v3.12).

When using RX DMA, the driver won't pass any data to the uart layer
until the buffer is flipped. When the port is shutdown, the dma buffers
are unmapped, but the head and tail of the ring buffer are not reseted.
Since the serial console will keep the port open,
