Subject: [PATCH 3/7 v3] i2c-eg20t: delete 10bit access processing
Date: Thu,  6 Oct 2011 15:56:28 +0900	[thread overview]
Message-ID: <1317884192-10694-4-git-send-email-tomoya-linux@dsn.lapis-semi.com> (raw)
In-Reply-To: <1317884192-10694-1-git-send-email-tomoya-linux@dsn.lapis-semi.com>

From: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com>

Linux I2C core doesn't support 10bit access formally.
Additionally, we can't test with 10bit mode.
This patch deletes the 10bit access processing.
