When neither CONFIG_OF nor CONFIG_ACPI are set, we get a harmless build warning: drivers/hwtracing/coresight/coresight-platform.c:26:12: error: unused function 'coresight_alloc_conns' [-Werror,-Wunused-function] static int coresight_alloc_conns(struct device *dev, ^ drivers/hwtracing/coresight/coresight-platform.c:46:1: error: unused function 'coresight_find_device_by_fwnode' [-Werror,-Wunused-function] coresight_find_device_by_fwnode(struct fwnode_handle *fwnode) As the code is useless in that configuration anyway, just add a Kconfig dependency that only allows building when at least one of the two is set. This should not hinder compile-testing, as CONFIG_OF can be enabled on any architecture.
