Subject: [PATCH 1/7] i2c-eg20t: Fix bus-idle waiting issue
Date: Wed, 21 Sep 2011 16:51:43 +0900	[thread overview]
Message-ID: <1316591509-4433-1-git-send-email-tomoya-linux@dsn.okisemi.com> (raw)

Currently, when checking whether bus is idle or not,
if timeout occurs,
this function always returns success(zero).
This patch fixes the issue.
