Subject: ACPI: acpi_table_parse_madt_family() is not MADT specific
X-Git-Tag: upstream/snapshot3+hdmi~35810^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6eb87fed52b7f6ac200eaa649cc3221e239d0113;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ACPI: acpi_table_parse_madt_family() is not MADT specific

acpi_table_parse_madt_family() is also used to parse SRAT entries.
So re-name it to acpi_table_parse_entries(), and re-name the
madt-specific variables within it accordingly.

cosmetic only.
