With the preceding core\nchange, reset waits for callbacks before input_unregister_device() can\nfree vi->idev. Recheck vi->ready after taking the lock again: keep draining\ncompleted events so an input packet is not truncated, but stop requeueing\nbuffers and kicking the queue.\n\nWith evdev attached, input_unregister_handle() currently waits for an RCU\ngrace period, which also waits out IRQ callbacks. This masks the lifetime\nbug on PCI and MMIO, but does not protect sleepable callbacks on other\ntransports."
