Subject: [PATCH] iio: core: use debugfs_remove_recursive() on IIO unload

From: Lars-Peter Clausen <lars@...afoo.de>

The debugfs dir may have multiple files/dirs attached to it. Use
debugfs_remove_recursive() to clean it up when the IIO module unloads.

Note: note sure if this needs a Fixes tag. It's been in here for ages now,
      so it may not be a big issue.
