The file in /usr/include is a user-space header, like every other
file in /usr/include.

The header file that is part of Comedi is a kernel space header.  Since
there's no decent place to install kernel headers, it's not installed,
and you have to copy it wherever it is needed.

-22 is -EINVAL, "Invalid argument".  See /usr/include/asm/errno.h.
