Subject: [PATCH 4/8] i2c: designware: set the common config before the if else
Date: Fri, 12 Aug 2016 17:02:50 +0300	[thread overview]
Message-ID: <1471010574-28598-5-git-send-email-jarkko.nikula@linux.intel.com> (raw)
In-Reply-To: <1471010574-28598-1-git-send-email-jarkko.nikula@linux.intel.com>

From: Weifeng Voon <weifeng.voon@intel.com>

DW_IC_CON_MASTER, DW_IC_CON_SLAVE_DISABLE and DW_IC_CON_RESTART_EN are
common config that need to be set for i2c designware master. So, configure
it first without having to repeat inside the if else.
