From bc57381e634782009b1cb2e86b18013699ada576 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 28 Apr 2011 16:41:14 +0900 Subject: usb: renesas_usbhs: use delayed_work instead of work_struct This delay is used to overjump debounce. And, this patch also move usbhsc_drvcllbck_notify_hotplug to global, because it will be called from other files.
