Subject: [PATCH 2/7] i2c: add info->archdata field
Date: Thu, 16 Oct 2008 21:12:53 +0400	[thread overview]
Message-ID: <20081016171253.GB5515@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20081016171222.GA24812@oksana.dev.rtsoft.ru>

If present the info->archdata is copied into the dev->archdata.
Some (OpenFirmware) platforms need it.
