From: Luo Jiaxing <luojiaxing@xxxxxxxxxx> [ Upstream commit cabe7c10c97a0857a9fb14b6c772ab784947995d ] Although if the debugfs initialization fails, we will delete the debugfs folder of hisi_sas, but we did not consider the scenario where debugfs was successfully initialized, but the probe failed for other reasons. We found out that hisi_sas folder is still remain after the probe failed. When probe fail, we should delete debugfs folder to avoid the above issue.
