Subject: [PATCH] iio: adis16480: Add debugfs_reg_access entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver is defining debugfs entries by calling
`adis16480_debugfs_init()`. However, those entries are attached to the
iio_dev debugfs entry which won't exist if no debugfs_reg_access
callback is provided.
