From 3c8c577fd2fcf3587f16a2a9e8174c9f849cb7a6 Mon Sep 17 00:00:00 2001 From: Shreyansh Chouhan Date: Mon, 24 May 2021 19:21:03 +0530 Subject: [PATCH] staging: rtl8723bs: refactor to reduce indents Reduce the number of indents in rtw_wlan_util.c file by refactoring the code. Moved the part of code that rearranged ac paramaters in the function WMMOnAssocResp to a separate function named sort_wmm_ac_params. It takes both the array of ac params and their indexes as arguments and sorts them. Has return type void. Moved the part of code that checked IE for realtek vendor in the function check_assoc_AP to a separate function named get_realtek_assoc_AP_vender. It takes a struct ndis_80211_var_ie * as an argument and returns u32 realtek vendor.
