[PATCH v2 0/4] acpi: Fix and cleanup in acpi.

[Tang Chen]

This patch-set fix the following problems:

1. Kill useless function save_add_info() which will block us from using
   numa when MEMORY_HOTPLUG is not configured.
2. acpi_table_parse() didn't check if @id is NULL.
3. Fix incorrect comment in acpi_table_parse(), and return -ENOENT if a
   table is not found.

And also did some cleanup.

change log v1 -> v2:
1. Use pr_fmt() to simply the SRAT message.
   Suggested by Joe Perches <joe@xxxxxxxxxxx>
2. Improve the log in patch 4, and change the return value of the stub of 
   acpi_table_parse() in linux/acpi.h
   Suggested by Toshi Kani <toshi.kani@xxxxxx>
3. Merge the two pr_{info|err} patches into one.
4. Remove on of the patch that has been merged by Rafael.

Tang Chen (4):
  acpi, numa, mem_hotplug: Kill save_add_info().
  acpi cleanup: Use pr_{info|err}() instead of printk() in
    arch/x86/mm/srat.c
  acpi: Check if @id is NULL in acpi_table_parse()
  acpi: Return -ENOENT in acpi_table_parse() and fix wrong comment.
