Yeah, I see where it is:

#define SMC_inb(a,p)  ({ \
	unsigned int __p = (unsigned int)((a)->iobase + (p<<1)); \
	unsigned int __v = *(volatile unsigned short *)((__p) & ~2); \
	if (__p & 2) __v >>= 8; \
	else __v &= 0xff; \
	__v; })


(p<<1) --> ((p)<<1)

Thanks for pointing this out.  Patch coming up.

regards,
Ben
