From c23837ce73a0cb84ab046a6c0aace30fdd1e26f0 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.
