[PATCH v3 2/7] ACPI: bus: implement for_each_acpi_dev_match when !ACPI
Posted by Ricardo Ribalda 1 year ago
Provide an implementation of for_each_acpi_dev_match that can be used
when CONFIG_ACPI is not set.

The condition `false && hid && uid && hrv` is used to avoid "variable
not used" warnings.

There should be a space after the semicolon. I guess this might depend on
who you ask. Either way,
