[PATCH 08/33] ACPI: Define acpi_put_table cleanup handler and acpi_get_table_ret() helper

[Shaopeng Tan (Fujitsu)]

> Define a cleanup helper for use with __free to release the acpi table when the
> pointer goes out of scope. Also, introduce the helper
> acpi_get_table_ret() to simplify a commonly used pattern involving
> acpi_get_table().
> 
> These are first used in a subsequent commit.
