From mboxrd@z Thu Jan 1 00:00:00 1970 From: Heiko Stuebner Subject: [PATCH] iommu/rockchip: silence attaching and detaching of devices Date: Thu, 21 May 2015 09:57:29 +0200 Message-ID: <1638542.l3M1oAbtAT@phil> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: iommu-bounces-cunTk1MwBs9QetFLy7KEm3xJsTq8ys+cHZ5vskTnxNA@public.gmane.org Errors-To: iommu-bounces-cunTk1MwBs9QetFLy7KEm3xJsTq8ys+cHZ5vskTnxNA@public.gmane.org To: Joerg Roedel Cc: linux-rockchip-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, iommu-cunTk1MwBs9QetFLy7KEm3xJsTq8ys+cHZ5vskTnxNA@public.gmane.org, linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, Daniel Kurtz , Tomasz Figa List-Id: iommu@lists.linux-foundation.org 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.
