Pull staging and IIO driver updates from Greg KH:
"Here's the big staging and iio driver update for 4.7-rc1.
I think we almost broke even with this release, only adding a few more
lines than we removed, which isn't bad overall given that there's a
bunch of new iio drivers added.
The Lustre developers seem to have woken up from their sleep and have
been doing a great job in cleaning up the code and pruning unused or
old cruft, the filesystem is almost readable :)
Other than that, just a lot of basic coding style cleanups in the
churn. All have been in linux-next for a while with no reported
issues"

For aesthetics, make the actual "request" function static and change
mite_request_channel_in_range() into a wrapper that calls the internal
function. Change the inline function that requests any free channel
into an export that also calls the internal function.

The dev_err() messages with pci_ioremap_bar() fails are just noise.
Remove them.
The 'use_win1' and 'fifo_size' dev_info() messages are also noise
but they may be useful when debugging. Change them to dev_dbg().
Absorb dump_chip_signnature() and change the pr_info() messages
to dev_dbg(). These also might be useful when debugging.

Currently all the drivers that use the mite driver have to call
mite_setup() after allocating and initializing the mite device
with mite_attach().
Move the mite_setup() call into mite_attach() to simplify the
drivers a bit and remove the need for the additional inline and
exported functions.
For aesthetics, move mite_setup2(), and rename it to mite_setup(),
so it's near mite_attach().

These functions are basically the comedi_driver (*attach)/(*detach)
for this driver.
For aesthetics, rename mite_alloc() to mite_attach() and pass the
comedi_device pointer to it instead of the pci_dev pointer.
Move the functions to the end of the file. This is typically where
a comedi_drivers (*attach)/(*detach) are located.
Add some docbook comments for these exported functions.

An allocated mite_channel will have its 'ring' member initialized
to point to the mite_ring that will be used for DMA. A non-allocated
mite_channel will have a 'ring' member set to NULL, either by a
channel release or due to the initial kzalloc of the 'mite' struct.
Refactor the code to use the mite_chan->ring to detect in a channel
is allocated and remove the unnecessary member.

sync the dma regadless of the status.
