Subject: mac80211: compete scan to cfg80211 if deferred scan fail to start
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3aed49ef17c7bc8397420529ac976fe058818e3d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac80211: compete scan to cfg80211 if deferred scan fail to start

We nulify local->scan_req on failure in __ieee80211_start_scan, so
__ieee80211_scan_completed will not call cfg80211_scan_done. Fix that.
