	Do we really need this chunk?

	Since triflex_get_info is already #ifdef'd out if CONFIG_PROC_FS is not 
set, we don't need to put that extra #ifdef on the .c file, since that 
function will not get used anyway.

	IIRC the policy for adding #ifdefs on .c files is when it's really 
necessary, and I don't really see the point for this (expect object size 
and an extra symbol defined, which I don't think it really hurts here).

	Cheers,

Felipe
