[Colin King]

From: Colin Ian King <colin.king at canonical.com>

[src/acpi/madt/madt.c:1185]: (style) The scope of the variable
  'skip' can be reduced.
[src/acpi/madt/madt.c:1187]: (style) The scope of the variable
  'len' can be reduced.
[src/acpi/madt/madt.c:1188]: (style) The scope of the variable
  'passed' can be reduced.
