Subject: [PATCH 1/6] scsi: hisi_sas: Change permission of parameter prot_mask

From: Xiang Chen <chenxiang66@...ilicon.com>

Currently the permission of parameter prot_mask is 0x0, which means that
the member does not appear in sysfs. Change it as other module parameters
to 0444 for world-readable.
