That requested_address_range field has been in the
acpi_rasf_patrol_scrub_parameter structure since 2018

Got moved/copied into the acpi_ras2_patrol_scrub_parameter structure
in 2023.

$ git blame include/acpi/actbl2.h | grep requested_address_range
e62f8227851da (Erik Kaneda 2018-02-15 13:09:26 -0800 2722) u64 requested_address_range[2];
