Subject: [Intel-wired-lan] [PATCH] iavf: Remove useless else if
Date: Fri, 9 Sep 2022 11:32:40 +0800 [thread overview]
Message-ID: <20220909033240.46329-1-jiapeng.chong@linux.alibaba.com> (raw)
The assignment of the else and else if branches is the same, so the else
if here is redundant, so we remove it and add a comment to make the code
here readable.
./drivers/net/ethernet/intel/iavf/iavf_main.c:2211:6-8: WARNING: possible condition with no effect (if == else).
Link: https://bugzilla.openanolis.cn/show_bug.cgi?id=2106
Reported-by: Abaci Robot <abaci@linux.alibaba.com>
Signed-off-by: Jiapeng Chong <jiapeng.chong@linux.alibaba.com>
