From: Ajay Singh <[email protected]>
This patch series mainly contains the change to handle the cfg80211
operation from its context. Now the WID commands are sent to firmware
directly from the caller context.
Also added few more patches to address the review comment received
earlier in series[1].

2.7.4
From: Ajay Singh <[email protected]>
Use mutex lock to protect the issuing of wid cmd to the firmware.
Currently the wid commands are synchronized by use of hif_workqueue work
queue.
Now, these changes are required to synchronize the access to wid
command, so the commands can be issued directly from cfg80211 context
and 'WILC_wq' thread.

Refactor code to avoid the use of static variables to configure the
'wiphy' structure. Now move static variables as part of 'priv' data so
it helped to maintain this information per interface.

From: Ajay Singh <[email protected]>
Refactor the code to avoid handling of add/edit stations using work
queue and now set the wid value from caller context.
Avoid making an extra copy of buffer and directly copy the data in
firmware expected format.

From: Ajay Singh <[email protected]>
Change the return type from u32 to void for wilc_hif_pack_sta_param() as
its value is not used. Also remove the use of extra pointer as it's not
required now.

Refactor code to handle dump_station() callback from cfg80211 context.
Instead of deferring issue of wid command now send it directly from cfg
context. Also making use of wilc_get_rssi() error status in case there
is a failure to post the wid command to the firmware.

From: Ajay Singh <[email protected]>
Avoid handling of inactive time related wid command in deferred manner.
Instead of posting the wid to workqueue now handle directly from the
caller context.

Avoid handling of WID_MAC_ADDR wid command in deferred approach. Instead
of posting the wid to workqueue now handle directly from the caller
context.

Use the correct reference to remain_ch variable in scan complete.
Passing 'msg->body.remain_on_ch' to handle_remain_on_chan is not
correct. So used the correct reference used to store roc related

Refactor code to handle the get_station() callback from cfg80211
context. Provided different API's to fetch the station statistics
information in sync or async call. From cfg80211 get_station() ops
callback calls the sync version of API.

From: Ajay Singh <[email protected]>
Refactor the code to avoid the use of an extra buffer to store the
connection related parameter. No need to call cfg80211_disconnected in
case of failure to send the wid command to firmware, an error status is
directly returned in cfg80211 connect callback.

2.7.4
From: Ajay Singh <[email protected]>
Refactor code to handle scan operation callback from cfg80211 context.
No need to maintain 'scan_attr' struct as the wid command is directly
sent to firmware from cfg80211 context.

From: Ajay Singh <[email protected]>
Refactor the connect related cfg callback to be called from cfg80211
context. No need to post connect command internally in case scan is in
progress instead simply return the error status in connect ops callback.
