include/asm is a link to an arch-specific directory, e.g. include/asm-i386

'find include -type f | xargs grep -H S3C2410_IICLC_SDA_DELAY5' or somesuch.

If the contents of the header are private to the module, then the header
belongs in the same directory as the module... '#include "my_header.h"'

If there are exported functions, data, or types, then the header belongs
in the include hierarchy.
