Andres Salomon 3209e061ad libertas: ensure we clean up a scan request properly ... Commit 2e30168b ("libertas: terminate scan when stopping interface") adds cleanup code to lbs_eth_stop to call cfg80211_scan_done if there's an outstanding cfg80211_scan_request. However, it assumes that the scan request was allocated via the cfg80211 stack. Libertas has its own internal allocation method, kept track of with priv->internal_scan. This doesn't set scan_req->wiphy, amongst other things, which results in hitting a BUG() when we call cfg80211_scan_done on the request. This provides a function to take care of the low-level scan_req cleanup details. We simply call that to deal with finishing up scan requests. The bug we were hitting was: [ 964.321495] kernel BUG at net/wireless/core.h:87! [ 964.329970] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 964.341963] pgd = dcf80000 ...
