Subject: [PATCH 042/108] scsi: hisi_sas: Modify the file permissions of
trigger_dump to write only
mainline inclusion
from mainline-v5.6-rc1
commit 3cd2f3c35d29a50947a975feffdcbe2d6a2418c0
category: feature
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EKNE
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3cd2f3c35d29a50947a975feffdcbe2d6a2418c0
----------------------------------------------------------------------
The trigger_dump file is only used to manually trigger the dump, and did
not provide a read callback function for it, so its file permission
setting to 600 is wrong,and should be changed to 200.
