From a1cc530d6d01db52d58b72ca342b568fdb0a7885 Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Thu, 25 Jun 2015 18:13:33 +0300 Subject: [PATCH] gpio: omap: prevent module from being unloaded while in use OMAP GPIO driver allowed to be built as loadable module, but it doesn't set owner field in GPIO chip structure. As result, module_get/put() API is not working and it's possible to unload OMAP driver while in use: omap_gpio 48051000.gpio: REMOVING GPIOCHIP WITH GPIOS STILL REQUESTED Hence, add missing configuration.
