## Overview

In the Linux kernel, the following vulnerability has been resolved:

iio: imu: adis16480: fix unprotected debugfs reads

The firmware_revision and firmware_date file operations are open coded
and never call debugfs_file_get(), which debugfs_create_file_unsafe()
requires. debugfs_remove_recursive() therefore does not wait for a read
in progress, and unbind frees the iio_dev underneath it.

Use debugfs_create_file() instead.
