From 10a3c45c6821d3ffe974bc5937693f18a16dd96c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 2 Mar 2011 10:59:48 +0100 Subject: [PATCH] ARM: iomux-imx31: allow pin_list to be const MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes the following warning in a mx3_defconfig build: arch/arm/mach-mx3/mach-bug.c: In function 'bug_board_init': arch/arm/mach-mx3/mach-bug.c:47: warning: passing argument 1 of 'mxc_iomux_setup_multiple_pins' discards qualifiers from pointer target type While at it remove some useless consts from unsigned int arguments.
