Subject: staging: rtl8723au: Do not embed struct wlan_bssid_ex in struct survey_event
X-Git-Tag: v3.17-rc1~123^2~2066
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=246879640e636256326221e70df8e1c3ef84ece0;p=~emulex%2Finfiniband.git

staging: rtl8723au: Do not embed struct wlan_bssid_ex in struct survey_event

Instead allocate it separately and reference it from survey_event.
This will allow for us to pass it on later without having to copy it.
