Thank you. This works for all cases but
+static ulong efi_do_enter(ulong asmlinkage (*entry)(void *image_handle,
+ struct efi_system_table *st))
+{
+ return 0;
+}
+
Here I get
WARNING: space prohibited between function name and open parenthesis '('
where I would have expected
WARNING: storage class should be at the beginning of the declaration
Best regards
