Subject: [PATCH 08/13] viafb: Introduce viafb_find_i2c_adapter()
Date: Fri, 23 Apr 2010 21:28:08 +0000 [thread overview]
Message-ID: <1272058093-20914-9-git-send-email-corbet@lwn.net> (raw)
In-Reply-To: <1272058093-20914-1-git-send-email-corbet@lwn.net>
The camera driver will need this to look up a specific adapter.
