Deskripsi (NVD)

In the Linux kernel, the following vulnerability has been resolved: Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag syzbot is reporting hung task at __input_unregister_device() [1], for iforce_close() waiting at wait_event_interruptible() with dev->mutex held is 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 to call wake_up() after clear_bit(). Fix this problem by introducing a helper that calls clear_bit() followed by wake_up_all().
