From mboxrd@z Thu Jan 1 00:00:00 1970 From: Josh Cartwright Subject: [PATCH 4/8] ARM: mvebu: make use of of_find_matching_node_and_match Date: Tue, 11 Feb 2014 10:24:02 -0600 Message-ID: <1392135847-30791-5-git-send-email-joshc@codeaurora.org> References: <1392135847-30791-1-git-send-email-joshc@codeaurora.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1392135847-30791-1-git-send-email-joshc@codeaurora.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Jason Cooper , Andrew Lunn , Gregory Clement , Sebastian Hesselbarth Cc: devicetree@vger.kernel.org, Russell King , linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org Instead of the of_find_matching_node()/of_match_node() pair, which requires two iterations through the match table, make use of of_find_matching_node_and_match(), which only iterates through the table once. While we're here, mark the of_system_controller table const.
