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)
