The generally accepted ways I've seen for static funcs in .c is:
#ifdef CONFIG_ACPI_APEI_PCIEAER
static void ghes_handle_aer(struct acpi_hest_generic_data *gdata)
{
...
}
#else
static void ghes_handle_aer(struct acpi_hest_generic_data *gdata) { }
#endif
This at least makes the function that does stuff easier to read and
gives you a spot to throw out a "Config not enabled" error if its
beneficial.
More of a style nit than anything else.
But either way,
