Smatch complains that "wcidx" value comes from the network and thus cannot be trusted. In this case, it actually seems to come from the firmware. If your wireless firmware is malicious then probably no amount of carefulness can protect you. On the other hand, these days we still try to check the firmware as much as possible. Verifying that the index is within bounds will silence a static checker warning. And it's harmless and a good exercise in kernel hardening. So I suggest that we do add a bounds check.

On usb device rate configuration for sampling is performed relying on a workqueue since it is not possible to access the device in the interrupt context. Move the configuration of the probe_rate flag in the workqueue in order to keep probe sampling in sync with actual rate configuration Fixes: eb99cc95 ("mt76: mt7615: introduce mt7663u support") Signed-off-by:
