In the Linux kernel, the following vulnerability has been resolved:Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flagsyzbot is reporting hung task at __input_unregister_device() [1], foriforce_close() waiting at wait_event_interruptible() with dev->mutex heldis blocking input_disconnect_device() from __input_unregister_device().It seems that the cause is simply that commit c2b27ef672992a20 ("Input:iforce - wait for command completion when closing the device") forgot tocall wake_up() after clear_bit().Fix this problem by introducing a helper that calls clear_bit() followedby wake_up_all().
