From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Subject: [PATCH 2/6] regulator: core: Print at debug level on debugfs creation failure Date: Mon, 1 Jun 2015 18:47:55 -0700 Message-ID: <1433209679-31389-3-git-send-email-sboyd@codeaurora.org> References: <1433209679-31389-1-git-send-email-sboyd@codeaurora.org> Return-path: Received: from smtp.codeaurora.org ([198.145.29.96]:57814 "EHLO smtp.codeaurora.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754394AbbFBBsC (ORCPT ); Mon, 1 Jun 2015 21:48:02 -0400 In-Reply-To: <1433209679-31389-1-git-send-email-sboyd@codeaurora.org> Sender: linux-pm-owner@vger.kernel.org List-Id: linux-pm@vger.kernel.org To: linux-arm-msm@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, Nishanth Menon , Viresh Kumar , Srinivas Kandagatla , Andy Gross , linux-pm@vger.kernel.org, Mark Brown , David Collins Failure to create a debugfs node is not an error, but we print a warning upon failure to create the node. Downgrade this to a debug printk so that we're quiet here. This allows multiple drivers to request a CPU's regulator so that CPUfreq and AVSish drivers can coexist. The downside of this approach is that whoever gets to debugfs first the others who come later to not have any debugfs attributes associated with them.
