From 444d2d33d8564f95df851ddaca80f640ca36934d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 18 Feb 2015 21:19:56 +0100 Subject: [PATCH] ARM: make of_device_ids const MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. So mark the non-const structs in arch/arm as const, too. While at it also add some __initconst annotations.
