Subject: staging: r8188eu: change return type of rtw_set_802_11_disassociate to void
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dcb18f5140ab7b4ea23417598c601b9468141d99;p=linux.git

staging: r8188eu: change return type of rtw_set_802_11_disassociate to void

Change return type of rtw_set_802_11_disassociate to void. This function
always returns 'true' no matter what, so there is no need to return a
value, and no need to check for it in the two call sites within
rtw_wx_set_mlme. Also, as we are no longer using ret in rtw_wx_set_mlme
except as the return value, just remove it and return 0 directly.
