From e9a80a02432f09225c6f5e5a6cfba80ded232ebb Mon Sep 17 00:00:00 2001 From: Naveen Krishna Ch Date: Thu, 26 Jun 2014 10:44:58 +0530 Subject: i2c: exynos5: remove extra line and fix an assignment This patch does the following in exynos5_i2c_message_start() function 1. Fixes an assignment As, "i2c_auto_conf" is initialized to '0' at the beginning of the function and HSI2C_READ_WRITE is defined as (1u << 16) Using "|=" for the first assignment is more readable. 2.
