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.
