i915 notification is executed in a spinlock, thus it must not sleep; i.e. we can't use kmalloc with GFP_KERNEL or such. For making it working properly, move the notification handler in a work, and handle it gracefully. We have already such a work, and it was used just at the start. This can be re-used in a more generic hotplug handling. Also, the patch adds the proper call of cancel_work_sync() to the destructor. Signed-off-by:
