Subject: [PATCH 01/17] cx23885: Return -ENXIO on slave nack
Date: Mon, 19 Jul 2010 21:08:58 -0400 [thread overview]
Message-ID: <1279588138.28153.3.camel@localhost> (raw)
In-Reply-To: <cover.1279586511.git.awalls@md.metrocast.net>
From: Jean Delvare <khali@linux-fr.org>
Documentation/i2c/fault-codes says that i2c adapter drivers should
return -ENXIO when no slave acks an address byte.
