From 227ab58cff3c26ec279598112887d6bcca677a0c Mon Sep 17 00:00:00 2001 From: Sylvain Rochet Date: Thu, 12 Feb 2015 18:54:04 +0100 Subject: [PATCH] usb: gadget: atmel_usba_udc: Fixed vbus_prev initial state If vbus gpio is high at init, we should set vbus_prev to true accordingly to the current vbus state. Without that, we skip the first vbus interrupt because the saved vbus state is not consistent.
