From 4e8bc211703d3c93689367745e8c07dc22c68dfc Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 23 Jul 2014 06:55:11 -0600 Subject: [PATCH] dm: Avoid activating devices in 'dm uclass' command This command currently activates devices as it lists them. This is not desirable since it changes the system state. Fix it and avoid printing a newline if there are no devices in a uclass.
