Subject: ACPI: OSL: Clean up the removal of unused memory mappings
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5003ad7172651e550103389b59b0dbeaebf65d00;p=linux.git

ACPI: OSL: Clean up the removal of unused memory mappings

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.
