Merge branches 'acpi-misc', 'acpi-cppc', 'acpi-docs', 'acpi-config' and 'acpi-apei' 

* acpi-misc:
  ACPI: Test for ACPI_SUCCESS rather than !ACPI_FAILURE
  ACPI: Use DEVICE_ATTR_<RW|RO|WO> macros

* acpi-cppc:
  ACPI: CPPC: initialise vaddr pointers to NULL
  ACPI: CPPC: add __iomem annotation to generic_comm_base pointer
  ACPI: CPPC: remove __iomem annotation for cpc_reg's address

* acpi-docs:
  Documentation: ACPI: add new rule for gpio-line-names

* acpi-config:
  ACPI: configfs: add missing check after configfs_register_default_group()

* acpi-apei:
  ACPI: APEI: ERST: remove unneeded semicolon
  ACPI: APEI: Add is_generic_error() to identify GHES sources
