From 332bf92b3338e140cbcfc25f69911e8ca59788c7 Mon Sep 17 00:00:00 2001 From: Hideki Iwamoto Date: Sun, 25 Sep 2005 16:56:43 +0200 Subject: [PATCH] [PATCH] i2c: Fix union i2c_smbus_data definition The i2c_smbus_data union block member has a comment stating that an extra byte is required for SMBus Block Process Call transactions. This has been true for three weeks around June 2002, but no more since, so it is about time that we drop this comment and fix the definition.
