From: Hanjun Guo Date: Tue, 21 Jul 2020 09:59:05 +0000 (+0800) Subject: ACPI: NUMA: Remove the useless sub table pointer check X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1c60f91c319d55058da3a0f6a361b6e6ee6b8c58;p=linux.git ACPI: NUMA: Remove the useless sub table pointer check In acpi_parse_entries_array(), the subtable entries (entry.hdr) will never be NULL, so for ACPI subtable handler in struct acpi_subtable_proc, will never handle NULL subtable entries. Remove those useless subtable pointer checks in the callback handlers. Signed-off-by: Hanjun Guo Signed-off-by: Rafael J.
