From a604d5f2f983f291514ef3f7530f7ea55a12ab03 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 30 Jan 2022 20:56:47 +0000 Subject: [PATCH] iio:adc:ad7091r: Move exports into IIO_AD7091R namespace. commit 8a0080af84d3fb2423f0b3b55eff666f545eb097 upstream. In order to avoid unnecessary pollution of the global symbol namespace move the core/library functions into a specific namespace and import that into the various specific device drivers that use them. For more information see https://lwn.net/Articles/760045/ An alternative here would be to conclude that we are unlikely to see support for the other ad7091r parts in the near future and just merge the two modules into one supporting just the i2c -5 variant.
