[PATCH 3/7 v3] i2c-eg20t: delete 10bit access processing
From: Tomoya MORINAGA
Date: Thu Oct 06 2011 - 02:52:11 EST
From: Tomoya MORINAGA <tomoya-linux@xxxxxxxxxxxxxxx>
Linux I2C core doesn't support 10bit access formally.
Additionally, we can't test with 10bit mode.
This patch deletes the 10bit access processing.
