Subject: [PATCH 03/21] ARM: tegra: Register drivers before devices
Date: Mon, 25 May 2015 16:53:07 +0200 [thread overview]
Message-ID: <1432565608-26036-4-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1432565608-26036-1-git-send-email-tomeu.vizoso@collabora.com>
So devices can be probed on demand, we need to have the drivers already
registered as we don't have enough information to register a driver on
demand.
