From 8373358c8d6027edb9f2e061d10a29b078c0e3b8 Mon Sep 17 00:00:00 2001 From: Luo Jiaxing Date: Tue, 24 Aug 2021 18:01:00 +0800 Subject: [PATCH] scsi: hisi_sas: Increase debugfs_dump_index after dump is completed The hisi_hba debugfs_dump_index member should increased after a dump insertion completed, and not before it has started, so fix the code to do so.
