From: Guangbin Huang <huangguangbin2@huawei.com> mainline inclusion from mainline-v5.15-rc1 commit 7f2f8cf6ef668c1c745e229023f98663f47aa702 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4BY3P CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- The function hclge_tm_dwrr_cfg() will be called twice in function hclge_ieee_setets() when map_changed is true, the calling flow is hclge_ieee_setets() hclge_map_update() | hclge_tm_schd_setup_hw() | hclge_tm_dwrr_cfg() hclge_notify_init_up() hclge_tm_dwrr_cfg() It is no need to call hclge_tm_dwrr_cfg() twice actually, so just return after calling hclge_notify_init_up().
