Doesn't this look odd to you?

If you really want to make this look nicer and more
intelligible, it's probably be better to use a more
symmetric form like:
if (dir == TO_XFER_BUF)
memcpy((unsigned char *)scsi_sglist(srb) + *offset,
buffer,
cnt);
else
memcpy(buffer,
(unsigned char *)scsi_sglist(srb) + *offset,
cnt);
or maybe
void *to;
void *from;
[...]
if (dir == TO_XFER_BUF) {
to = (unsigned char *)scsi_sglist(srb) + *offset;
from = buffer;
} else {
to = buffer;
from = (unsigned char *)scsi_sglist(srb) +
*offset;
}
memcpy(to, from, cnt);
or maybe
void *to;
void *from;
[...]
to = (unsigned char *)scsi_sglist(srb) + *offset;
from = buffer;
if (dir != TO_XFER_BUF)
swap(to, from);
memcpy(to, from, cnt);
