Subject: ACPICA: cast the result of the pointer difference to u32
Patch-mainline: v5.7-rc1
Git-commit: 45bbbbe2d5bcfe72754da275298f5de9120a4c31
References: jsc#SLE-16407
Altnatively we could declare aml_length as acpi_size, but then one
would need to cast at the assignment for method_obj->method.aml_length
ACPICA commit 72805936603fcf84e98f1b89bf99b5101af27fb8
