Currently the IIO buffer interface only allows non-blocking reads. This patch

data is available and will wait for the buffer implementation to signal that new
data is available by waking up the buffers waitqueue.

iio: kfifo_buf: Implement data_available() callback

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.

iio: Add data_available callback for buffers

This patch adds a new data_available() callback to the iio_buffer_access_funcs
struct. The callback is used to indicate whether data is available in the buffer
for reading. It is meant to replace the stufftoread flag from the iio_buffer
struct. The reasoning for this is that the buffer implementation usually can
determine whether data is available rather easily based on its state, on the
other hand it can be rather tricky to update the stufftoread flag in a race free
way.

VME: Provide access to VME bus enumeration and fix vme_user match function

The match function for vme_user is completely wrong. It will blindly bind
against the first VME slot on each bus (at this point that would be just the
first bus as the driver can only handle one bus).

The original intention (before some major subsystem changes) was that the
driver bind against the slot to which the bridge was attached in the VME
system and to the bus(es) provided via the "bus" module parameter.

To do this cleanly (i.e. without poking arround in the subsystems internal
stuctures) a functionality has been added to provide access to the bus
enumeration.
