Comment say it was copied from tile which I think was just recently
removed.  But looking at older copy, tile has "struct pt_regs regs"
whereas riscv has "struct pt_regs *regs" and so tile needed the & and
riscv does not, but only one of the two ampersands was removed in the
riscv port.  My patch removes the other one.
