patch "iio: buffer: Fix wait_queue not being removed" added to char-misc-linus

This is a note to let you know that I've just added the patch titled

iio: buffer: Fix wait_queue not being removed

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

In the edge case where the IIO device is unregistered while we're buffering, we were directly returning an error without removing the wait queue. Instead, set 'ret' and break out of the loop.
