[PATCH 0/3 v2] usb/hid-core: drain URB queue when going to suspend

In some situations, trying to suspend a laptop with an attached USB keyboard
would fail if both NumLock and CapsLock LEDs were lit.
This was due to a race condition between asynchronously submitted
LED-manipulating CTRL URBs and the suspend process.

This is a different solution to the same problem highlighted here:
https://lkml.org/lkml/2011/9/2/391

These patches are against Jiri's hid/for-next branch.

Daniel Kurtz (3):
  HID: usbhid: remove LED_ON
  HID: usbhid: hid-core: submit queued urbs before suspend
  HID: usbhid: defer LED setting to a workqueue

Differences since v1:
  * Rebase on hid/for-next
  * Solve race with usbhid_stop() [reported by Oliver Neukum]
