Subject: [PATCH net-next 1/1] net: stmmac: Remove redundant checking for rx_coalesce_usecs
Date: Tue, 23 May 2023 02:19:52 -0400 [thread overview]
Message-ID: <20230523061952.204537-1-yi.fang.gan@intel.com> (raw)
The datatype of rx_coalesce_usecs is u32, always larger or equal to zero.
Previous checking does not include value 0, this patch removes the
checking to handle the value 0.
