[ CC HID folks ]

I am seeing this call-trace when compiling a Linux v4.2.y or Linux
v4.3-rcN kernel with my llvm-toolchain and llvmlinux-amd64 patchset.
CLANG sometimes catches things which GCC does not.

Not sure if this is a workqueue or hid issue...

Lai pointed to these parts in...

[ drivers/hid/usbhid/hid-core.c ]

...
void usbhid_close(struct hid_device *hid)
{
struct usbhid_device *usbhid = hid->driver_data;

mutex_lock(&hid_open_mut);

/* protecting hid->open to make sure we don't restart
* data acquistion due to a resumption we no longer
* care about
*/
spin_lock_irq(&usbhid->lock);
if (!--hid->open) {
spin_unlock_irq(&usbhid->lock);
hid_cancel_delayed_stuff(usbhid); <--- XXX
if (!(hid->quirks & HID_QUIRK_ALWAYS_POLL)) {
usb_kill_urb(usbhid->urbin);
usbhid->intf->needs_remote_wakeup = 0;
}
} else {
spin_unlock_irq(&usbhid->lock);
}
mutex_unlock(&hid_open_mut);
}
...
static void hid_cancel_delayed_stuff(struct usbhid_device *usbhid)
{
del_timer_sync(&usbhid->io_retry);
cancel_work_sync(&usbhid->reset_work);
}
...

So can people from HID look at this, too?

Thanks.
