Subject: [PATCH] net: dsa: Remove unsigned expression compared with zero
Date: Wed, 19 May 2021 18:49:51 +0800	[thread overview]
Message-ID: <1621421391-36681-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)

Variable val is "u32" always >= 0, so val >= 0 condition are redundant.

Clean up the following coccicheck warning:

./drivers/net/dsa/qca8k.c:732:5-8: WARNING: Unsigned expression compared
with zero: val >= 0.
