Btw. what kind of compiler/make switches are you using so that I can see

These are Sparse warnings, not from GCC.
I compiled the code (the original version), but I do not get that
"Should it be static?" warning:

Kernel: arch/x86/boot/bzImage is ready (#2)
I've seen that warning at different other code - but not in bcm.c & raw.c
I downloaded & compiled the latest sparse source. But still no "static"
warning. Any idea?
Best regards,
Oliver
