On normal\nremoval hid_device_remove() has already cleared io_started before the\ndevres group is released, so an unconditional call would otherwise hit\nthe !io_started path and emit a spurious \"io already stopped\" warning\non every removal. The guard preserves the probe-failure balancing,\nwhere io_started is still set after hid_device_io_start(), while\nstaying silent on the normal removal path."
