Subject: [PATCH net-next] igb: make igb_set_fc_watermarks() return void
Date: Thu, 7 May 2020 19:09:15 +0800 [thread overview]
Message-ID: <20200507110915.38349-1-yanaijie@huawei.com> (raw)
This function always return 0 now, we can make it return void to
simplify the code. This fixes the following coccicheck warning:
drivers/net/ethernet/intel/igb/e1000_mac.c:728:5-12: Unneeded variable:
"ret_val". Return "0" on line 751
