## Description

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