This series is a resubmission. No changes were being made compared
to the previous series.
* handling firmware halt indication.
* cleanup scan related code.
The series applies to the master branch of the wireless-drivers-next
repository and is intended for v4.15 kernel.
Arend Van Spriel (6):
brcmfmac: handle FWHALT mailbox indication
brcmfmac: cleanup brcmf_cfg80211_escan() function
brcmfmac: use msecs_to_jiffies() instead of calculation using HZ
brcmfmac: get rid of brcmf_cfg80211_escan() function
brcmfmac: get rid of struct brcmf_cfg80211_info::active_scan field
brcmfmac: move configuration of probe request IEs
Franky Lin (1):
brcmfmac: disable packet filtering in promiscuous mode

The function brcmf_cfg80211_escan() was always called with a non-null
request parameter and null pointer for this_ssid parameter. Clean up
the function removing the dead code path.

The firmware uses a mailbox to communicate to the host what is going
on. In the driver we validate the bit received. Various people seen
the following message:
brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012
Bit 4 is cause of this message, but this actually indicates the firmware
has halted. Handle this bit by giving a more meaningful error message.

The function brcmf_cfg80211_escan() is only called by brcmf_cfg80211_scan()
so there is no reason to split in two function especially since the latter
does not do an awful lot.
