My driver of interest fails to probe for v6.0-rc1 for ACPI FW:
[    5.373722] hisi_sas_v2_hw HISI0162:01: could not get property sas-addr

from a device_property_read_u8_array() call

The following fixes it:

Tested-by: John Garry <john.garry@huawei.com>

I'm just sending a separate mail to highlight this issue as I spent an 
appreciable time bisecting and want others to avoid that. And I could 
not find the fix mail for some reason, even though I subscribe to the 
acpi list.
