From cac089f9026e9ddb3481daf08f0fc4e5949fa1af Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 23 Apr 2015 16:56:22 -0700 Subject: gpio: omap: Allow building as a loadable module We currently get all kinds of errors building the omap gpio driver as a module starting with: undefined reference to `omap2_gpio_resume_after_idle' undefined reference to `omap2_gpio_prepare_for_idle' ... Let's fix the issue by adding inline functions to the header. Note that we can now also remove the two unused functions for omap_set_gpio_debounce and omap_set_gpio_debounce_time. Then doing rmmod on the module produces further warnings because of missing exit related functions. Let's add those. And finally, we can make the Kconfig entry just a tristate option that's selected for omaps.
