From bec8a5a22640325e86cf5b737c18888747631099 Mon Sep 17 00:00:00 2001
From: Krzysztof Kozlowski <k.kozlowski@samsung.com>
Date: Fri, 10 Jul 2015 13:53:06 +0900
Subject: [PATCH] coccinelle: api: extend spatch for dropping unnecessary owner

i2c_add_driver (through i2c_register_driver) sets the owner field so we
can drop it also from i2c drivers, just like from platform drivers.
