From 71abf71e9e634a55b1156f4aaae6122207f4b8ef Mon Sep 17 00:00:00 2001 From: luo penghao Date: Thu, 4 Nov 2021 06:14:11 +0000 Subject: [PATCH] mac80211: Remove unused assignment statements The assignment of these three local variables in the file will not be used in the corresponding functions, so they should be deleted.
