From: Harshit Mogalapalli <harshit.m.mogalapalli@oracle.com> stable inclusion from stable-v6.6.2 commit 2584e54502e1c77ce143d5874520f36240395e6f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit b7c3ca3553d1de5e86c85636828e186d30cd0628 ] The value of 'ret' is zero when of_hte_req_count() fails to get number of entitties to timestamp. And returning success(zero) on this failure path is incorrect.
