From 09271f4eea9cd11543ae91db02727a3b20b29d03 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 29 Jan 2015 10:29:18 -0600 Subject: usb: dwc3: gadget: add missing spin_lock() commit 5c7b3b02de766a8634708953e805399e3544a290 upstream. commit 8e74475b0e0a (usb: dwc3: gadget: use udc-core's reset notifier) added support for the new UDC core's reset notifier to dwc3 but while at it, it removed a spin_lock() from dwc3_reset_gadget() which might cause an unbalanced spin_unlock() further down the line Fixes: 8e74475b0e0a (usb: dwc3: gadget: use udc-core's reset notifier) Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman --- drivers/usb/dwc3/gadget.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers') diff --git a/drivers/usb/dwc3/gadget.c b/drivers/usb/dwc3/gadget.c index 8f65ab3a3b92..4efd3bd35586 100644 --- a/drivers/usb/dwc3/gadget.c +++ b/drivers/usb/dwc3/gadget.c @@ -2043,6 +2043,7 @@ static void dwc3_resume_gadget(struct dwc3 *dwc) if (dwc->gadget_driver && dwc->gadget_driver->resume) { spin_unlock(&dwc->lock); dwc->gadget_driver->resume(&dwc->gadget); + spin_lock(&dwc->lock); } } -- cgit v1.2.3
