- 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.
