From 35d8b2e6b8e86b0d5126f36613b5202d4eb978b6 Mon Sep 17 00:00:00 2001 From: Laurent Riffard Date: Sat, 26 Nov 2005 20:34:05 +0100 Subject: [PATCH] i2c: Drop i2c_driver.{owner,name}, 1 of 11 We should use the i2c_driver.driver's .name and .owner fields instead of the i2c_driver's ones. This patch updates the core of the i2c drivers: it removes .name and .owner fields from the struct i2c_device and modify various functions to use struct device fields instead.
