sending message we can know the send status via error

This will also help SBA-RAID to use "txdone_ack" method
whenever mailbox controller supports it.

Currently, sba_process_deferred_requests() handles both pending
and completed sba_request which is unnecessary overhead for
sba_issue_pending() because completed sba_request handling is

sba_proces
The SBA_REQUEST_STATE_RECEIVED state is now redundant because
received sba_request are immediately freed or moved to completed
list in sba_process_received_request().
This patch removes redundant SBA_REQUEST_STATE_RECEIVED state.

When a nf_conntrack_l3/4proto parameter is not on the left hand side
of an assignment, its address is not taken, and it is not passed to a

This patch is created to solve CamelCase issue. The
variables 'IEs' and 'IELength' of struct wlan_bssid_ex
are replaced with 'ies' and 'ie_length' to solve the
CamelCase issue and these changes are applied to all the
places where these variables are referenced inside the
rtl8188eu driver.
