From 00759f796b5f80dbeee615d2f16f9fa4e63b3161 Mon Sep 17 00:00:00 2001 From: blogic <blogic@3c298f89-4303-0410-b956-a3cf2f4a3e73> Date: Thu, 1 Aug 2013 14:31:28 +0000 Subject: [PATCH] gpio-button-hotplug: use gpio_button_get_value() to initialize last_state. TL-WR720N-v3 has a slider switch composed of 2 GPIO buttons which can be used to swtich between 3 positions. At leat 1 button is in pressed state in any of those positions. Initialize 'last_state' as 0 (released) will cause the device to automatically enter failsafe mode on every bootup.
