This patch implements the data_available() callback for the kfifo buffer instead of using the stufftoread flag. The kfifo used by the buffer already knows whether it is empty or not based on the position of its read and write pointer. Using this makes it a lot easier to tell whether data is available or not and it is not necessary to take special measures to ensure that no race conditions between reading and writing from the buffer occur. Note, that we still have to take the buffers lock to protect against concurrent resizeing of the kfifo.
