Alexandru Ardelean 62a30a292a iio: buffer: fix attach/detach pollfunc order
The original patch was error-ed by the submitter (me) and not by the author
(Lars).
After looking through the discussion logs (on email), it seems that this
order was wrong for the start, even though the order implemented in the
drivers was correct.

Discussions:
- first RFC: https://lore.kernel.org/linux-iio/20180622135322.3459-1-alexandru.ardelean@analog.com/
- 2nd patch: https://lore.kernel.org/linux-iio/20181219140912.22582-1-alexandru.ardelean@analog.com/
- final patch-sets:
  https://lore.kernel.org/linux-iio/20200522104632.517470-1-alexandru.ardelean@analog.com/
  https://lore.kernel.org/linux-iio/20200525113855.178821-1-alexandru.ardelean@analog.com/

The last one was applied.

The idea is that pollfunc should be attached before calling the
'indio_dev->setup_ops->postenable' hook and should be detached after
calling the 'indio_dev->setup_ops->predisable' hook.

While the drivers were updated to take this into account, the change to the
IIO core was somehow omitted and was made wrong.

This change fixes the order to the proper form.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
