From 143c253f42bad20357e7e4432087aca747c43384 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Sun, 7 Mar 2021 00:40:12 -0800 Subject: net: hisilicon: hns: fix error return code of hns_nic_clear_all_rx_fetch() When hns_assemble_skb() returns NULL to skb, no error return code of hns_nic_clear_all_rx_fetch() is assigned. To fix this bug, ret is assigned with -ENOMEM in this case. Reported-by: TOTE Robot Signed-off-by: Jia-Ju Bai Signed-off-by: David S.
