From d463c6ff88108d187c73396280f5dae8b4a78e65 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 27 Nov 2013 15:46:06 +0100 Subject: [PATCH] gpio-lynxpoint: Allow building as a module Change CONFIG_GPIO_LYNXPOINT from bool to tristate so that the gpio-lynxpoint driver can be built as a module. Add the required glue: an exit function to unregister the driver, and module information.
