To tell the truth, I dislike this style too.... OK, I'll fix.
I reformatted to fix " CHECK: Alignment should match open parenthesis"
style issue.
I thought the following style is easy to exceed 80 columns, I opted
the above style.

Its signature is
acpi_status(*acpi_walk_resource_callback) (struct acpi_resource * resource,
void *context);
