Subject: ACPI: OSL: Use deferred unmapping in acpi_os_unmap_generic_address()
Patch-mainline: v5.9-rc1
Git-commit: f4334efb11a01b37af90e2ad459ee3bb6337211d
References: jsc#SLE-16407
There is no reason (knwon to me) why any of the existing users of
acpi_os_unmap_generic_address() would need to wait for the unused
memory mappings left by it to actually go away, so use the deferred
unmapping of ACPI memory introduced previously in that function.
