From 608c783aaa0abe39e3672f65b786cdade8db6df9 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 18 Apr 2006 23:18:54 +0100 Subject: [PATCH] [ARM] 3479/1: Corgi SSP: Fix potential concurrent access problem Patch from Richard Purdie corgi_ssp_probe() should not access GPDR directly but should use pxa_gpio_mode() which has appropriate locking and other safeguards.
