<br />
wifi: iwlwifi: mvm: fix P2P-Device binding handling<br />
<br />
Our binding handling for P2P-Device can run into the following<br />
scenario, as observed by our testing:<br />
<br />
- a station interface is connected on some channel<br />
- the P2P-Device does a remain-on-channel (ROC) on that channel<br />
- the ROC ends, and the P2P-Device is removed from the binding,<br />
but the phy_ctxt pointer is left around as a PHY cache so we<br />
don&#39;t need to recalibrate to the channel again and again in<br />
case it&#39;s not shared<br />
- a binding update by the station interface, even a removal,<br />
will re-add the P2P-Device to the binding<br />
- the P2P-Device is removed, which removes the PHY context, but<br />
it&#39;s still in the binding so the firmware crashes<br />
<br />
Since the P2P device is removed from the binding and only re-<br />
added by unrelated code, but we want to keep the phy_ctxt around<br />
as a cache for future ROC usage, fix it by adding a boolean that<br />
indicates whether or not the P2P-Device should be added to the<br />
binding, and handle that in the binding iterator. That way, the<br />
station interface cannot re-add the P2P-Device to the binding<br />
when that isn&#39;t active.
