From d564baee2984098c73fd0e55bc5c8a890878ef3b Mon Sep 17 00:00:00 2001 From: Laurent Riffard Date: Sun, 18 Dec 2005 16:49:30 +0100 Subject: [PATCH] [PATCH] i2c: drop empty i2c_driver.command implementations Given that implementing i2c_driver.command is optional, there is no point in an empty implementation thereof.
