From c3106cac2a80381e860adbd416e166f778b8806a Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Sat, 11 Jan 2020 16:33:52 +0800 Subject: net: hns3: modify hclge_func_reset_sync_vf()'s return type to void When synchronizes with VFs fail before PF function reset, PF driver should go on its function reset, otherwise it can not run normally anymore. So, hclge_func_reset_sync_vf() should not affect the processing of PF reset, this patch modifies its return type to void. Signed-off-by: Huazhong Tan Signed-off-by: David S.
