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
