+Subject: [PATCH] brcmfmac: Handle status == BRCMF_E_STATUS_ABORT in
+ cfg80211_escan_handler
+
+If a scan gets aborted BRCMF_SCAN_STATUS_BUSY gets cleared in
+cfg->scan_status and when we receive an abort event from the firmware
+the BRCMF_SCAN_STATUS_BUSY check in the cfg80211_escan_handler will
+trigger resulting in multiple errors getting logged.
+
+Check for a status of BRCMF_E_STATUS_ABORT and in this case simply
+cleanly exit the cfg80211_escan_handler. This also avoids a
+BRCMF_E_STATUS_ABORT event arriving after a new scan has been started
+causing the new scan to complete prematurely without any data.
