iommu/rockchip: silence attaching and detaching of devices
From: Heiko Stuebner <heiko@...> Date: Thu, 21 May 2015 09:52:19 +0200
Commit-Message
Currently the driver emits a log line every time a device attaches or detaches - which happens at every unblank/blank of the drm for example. The message itself also has no real value to the average user and is merely useful when debugging a problem, so make it a dev_dbg instead. Signed-off-by: Heiko Stuebner <heiko@...>
