From 16b551dd22cc7edacb952f7a2e175f36c3aa4bdb Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 24 Jul 2013 17:50:50 -0700 Subject: ARM: shmobile: armadillo800eva: Don't request GPIO 166 in board code 89ae7b5bbd3e65bc6ab7a577ca5ec18569589c8c (ARM: shmobile: armadillo800eva: Register pinctrl mapping for INTC) mistakenly requests GPIO 166 in board code, most probably due to a wrong merge conflict resolution. As the GPIO is passed to the st1232 driver through platform data and requested by the driver, there's no need to request it in board code. Fix it.

The reason is apparently that commit ca7bb309485e4ec89a9addd47bea (ARM: shmobile: bockw: add SDHI0 support) matched the previous version of commit 564617d2f92473031d035deb273da5 (sh-pfc: r8a7778: add SDHI support). Add the missing pin groups according to the BOCK-W board schematics.

However, this is not true of gpio_buttons, a reference to it rather than its value is duplicated when lager_keys_pdata is duplicated. This avoids accessing freed memory if gpio-key events occur after unused kernel memory is freed late in the kernel's boot. This but was added when support for gpio-keys was added to lager in c3842e4fcbb7664276443b79187b7808c2e80a35 ("ARM: shmobile: lager: support GPIO switches") which was included in v3.11-rc1.
