[PATCH 3/3] ACPI: OSL: Clean up the removal of unused memory mappings
From: Rafael J. Wysocki
Date: Thu Jul 02 2020 - 08:17:41 EST
From: "Rafael J. Wysocki" <rafael.j.wysocki@xxxxxxxxx>
Fold acpi_os_map_cleanup_deferred() into acpi_os_map_remove() and
pass the latter to INIT_RCU_WORK() in acpi_os_drop_map_ref() to make
the code more straightforward.
No intentional functional impact.
