Subject:    [PATCH 15/16] iio:light:st_uvis25: Move exports to IIO_UVIS25 namespace
From:       Jonathan Cameron <jic23 () kernel ! org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

In order to avoid unnecessary pollution of the global symbol namespace
move the common/library functions into a specific namespace and import
that into the bus specific device drivers that use them.

For more information see https://lwn.net/Articles/760045/
