Subject: [BUG] Issue with commit 923044133367 ("ACPI: property: Unify integer value reading functions")

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 <[email protected]>

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.

Appreciated, thanks a lot!

I'm out of office this week, but I'll be pushing the fix for -rc3 next week.

Thanks!
