[PATCH] staging: rtl8723bs: Fix Unneeded variable: "ret". Return "0"

From: Shobhit Kukreti
Date: Thu Jun 06 2019 - 23:15:06 EST


coccicheck reported Unneeded variable ret at rtl8723bs/core/rtw_ap.c:1400.
Function "rtw_acl_remove_sta" always returns 0. Modified return type of the
function to void.
