ACPI: bus: implement for_each_acpi_consumer_dev when !ACPI

ribalda · rafaeljw · commit 46d10e5f9c34 · 2024-12-19T20:59:36.000+01:00
Provide an implementation of for_each_acpi_consumer_dev that can be use used when CONFIG_ACPI is not set. The expression `false && supplier` is used to avoid "variable not used" warnings.
