[PATCH 04/23] staging: wilc1000: remove extra enums defined for ieee80211_eid

[Ajay Singh]

Cleanup patch to make use of existing enum 'ieee80211_eid' instead of
adding new enum in WILC for element ID's.

The below mapping is same to remove extra enum in WILC.

SUPP_RATES_IE   	-> WLAN_EID_SUPP_RATES
EXT_SUPP_RATES_IE	-> WLAN_EID_EXT_SUPP_RATES
HT_CAPABILITY_IE	-> WLAN_EID_HT_CAPABILITY
RSN_IE			-> WLAN_EID_RSN
WPA_IE			-> WLAN_EID_VENDOR_SPECIFIC
WMM_IE			-> WLAN_EID_VENDOR_SPECIFIC
P2P_IE			-> WLAN_EID_VENDOR_SPECIFIC

Also remove enum 'info_element_id' as its same as 'ieee80211_eid', below
the mapping of elements of enums which are used.

ITIM -> WLAN_EID_TIM
IDSPARMS -> WLAN_EID_DS_PARAMS

[PATCH 05/23] staging: wilc1000: rename goto to avoid leading '_' in label name

[Ajay Singh]

Cleanup patch to avoid use of leading '_' in goto label name. Also used
proper string for lable names.

This isn't related to your patch but this goto doesn't appear to make
any sort of sense.  I have no idea what was intended.

Thanks for pointing it out. I will include these changes in separate
patchset.

Yes, the position of goto label can be moved just before
wilc_wlan_handle_rxq(wilc), as 'ret' will always be '0' when goto
statement is executed.

Actually earlier there were few more goto statement in this function
and single label 'end' was used to handle for different cases. But in
previous cleanup patches those cases were removed.
Now this function can be further refactor by either moving
goto label before wilc_wlan_handle_rxq(wilc) or avoid goto use by
adding the rx_buffer validation along with size check.

i.e 

end:
    wilc_wlan_handle_rxq(wilc)


OR

	if (size > 0 && wilc->rx_buffer) {

	....
	}
    	wilc_wlan_handle_rxq(wilc)

Actually looking at it now, you could probably just remove the if
statement.  Hopefully wilc->rx_buffer is non-NULL at this point? Is
there really any need to call wilc_wlan_handle_rxq() when we haven't
called wilc_wlan_rxq_add()?

Yes, wilc->rx_buffer would be non NULL value as its only one time
allocated buffer. wilc_wlan_handle_rxq() was called without
wilc_wlan_rxq_add() just as a fail safe to ensure there are no pending
packets in the queue.

The only thing is wilc->quit can be set.  Otherwise if ->rx_buffer is
NULL it would just result in a NULL dereference.  (We are deep into
hypotheticals here because we're discussing impossible code).

[PATCH 21/23] staging: wilc1000: use 'int' inplace of 's32' date type

[Ajay Singh]

Cleanup patch to use 'int' instead of 's32' to have the same data type
based on its usage.
