From 17f4a5c47f28de9ea59182f48d07f8c44ee5dcc9 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Mon, 22 Sep 2014 19:41:00 +0200 Subject: [PATCH] i2c: move acpi code back into the core Commit 5d98e61d337c ("I2C/ACPI: Add i2c ACPI operation region support") renamed the i2c-core module. This may cause regressions for distributions, so put the ACPI code back into the core.
