ACPI: Introduce acpi_unload_parent_table() usages in Linux kernel
ACPICA has implemented acpi_unload_parent_table() which can exactly replace
the acpi_get_id()/acpi_unload_table_id() implemented in Linux kernel. The
acpi_unload_parent_table() has been unit tested in ACPICA simulation
environment.
This patch can also help to reduce the source code differences between
Linux and ACPICA.
