From a386267a2ceea33d76fa2b7f1c2e72a858fcb68e Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 27 May 2013 15:53:32 +0200 Subject: [PATCH] pinctrl: pinconf: take the right mutex The pinconf_dgb_config_print() takes the per-pincontroller mutex, when what it wants to take is actually the pin maps mutex.
