This isn't a way I supposed. In principle, you must not touch
include/sound/*.h files. These are just copies from Linux kernel

For any lacking linux/*.h files, you can create the own in somewhere
locally by detecting in configure script. For example, keep a
directory include-compat/linux/types.h, and add -Iinclude-compat for
