[PATCH] iio: fix SPHINX kernel-docs build warning

From: Tobin C. Harding
Date: Tue Dec 19 2017 - 01:00:18 EST

When building kernel documentation sphinx emits the following warnings

No description found for parameter 'iio_dev'
Excess function parameter 'indio_dev' description in 'iio_device_register'

These warnings are caused by a macro with a different argument identifier to the
one listed in the kernel-docs.

Change macro argument to be the same as the docs.
