The acpi_get_table() should be coupled with acpi_put_table() if the
mapped table is not used for runtime after the initialization, or the
error path or the initialization, to release the table mapping.

This patchset just scan for every acpi_get_table() in ACPI subsystem to
see if acpi_put_table() is needed, this is not urgent and I think can
be merged for 5.8 if this patchset makes sense.

Hanjun Guo (9):
  ACPI: LPIT: Put the low power idle table after using it
  ACPI: watchdog: Put the watchdog action table after parsing
  ACPI: APEI: Put the boot error record table after parsing
  ACPI: APEI: Put the error injection table for error path and module
    exit
  ACPI: APEI: Put the error record serialization table for error path
  ACPI: APEI: Put the HEST table for error path
  ACPI: EC: Put the ACPI table after using it
  ACPI: scan: Put SPCR and STAO table after using it
  ACPI: sleep: Put the FACS table after using it
