Glen Lee 03efae328d staging: wilc1000: set hif_drv before it is used
We are using hif_drv of vif, so it needs to be set before it is used.
Set hif_drv to vif->hifdrv soon after it is allocated.

Glen Lee cd2920a50c staging: wilc1000: remove wilc of struct host_if_drv
vif has wilc in it's members so no need to have wilc in host_if_drv.
It is redundant so just remove it and use wilc of vif.

To use wilc_get_vif_idx instead of the last get_id_from_handler, join_req_drv

As a result, get_id_from_handler is not used anymore, so remove it.

Glen Lee eb9939b760 staging: wilc1000: use vif index to communicate with wilc device
We now have vif index in all functions related with host interface thread.
wilc_get_vif_idx and wilc_get_vif_from_idx are added to get id and vif
respectively.
Relace get_id_from_handler with wilc_get_vif_idx and get_handler_from_id with
wilc_get_vif_from_idx. Remove unused function get_handler_from_id as well.
We get vif where wilc_get_vif_from_idx is called, so pass vif to msg.vif.

There are two get_id_from_handler left. They will be removed in later patch.

Glen Lee 71130e812a staging: wilc1000: take vif instead of drv in hostIFthread
In the first patch, we sent vif to hostIFthread. we can use vif instead of
drv in the all functions which handle the commands from cfg operations.
Change first argument host_if_drv with wilc_vif and use hif_drv of wilc_vif.
Pass vif to the functions as well.
In case of timer callback functions, set vif to the data and use vif instead
of hif_drv.
Lastly, initialize u32RcvdAssocRespInfoLen since changing hif_drv with vif
causes one uninitialied build warning.
Now we have vif that currently being used so we can use interface index of
wilc_vif to send to wilc device.

An (*insn_read) can only happen if the subdevice is in a non-busy state,

The (*insn_read) only needs to enable the software trigger before reading

Change the return type to void, this function always succeeds and the
caller does not check the return value anyway.

Fix the initial programming of the control register. The SW bit enables
the software trigger and should not be set here. Setting CNT0 selects the
external clock source for counter 0 (the user counter). It makes more
sense to select the internal 1 MHz clock.

Remove the unnecessary initialization of the private data members. This
function is only called during the (*auto_attach) after the private
data was kzalloc'ed.

Remove the redundant clearing of the A/D FIFO and pending interrupts.
Just do it once.
