riscv: no __user for probe_kernel_address()
In is_valid_bugaddr(), probe_kernel_address() is called with the PC casted to (bug_inst_t __user *) but this function only take a plain void* as argument, not a __user pointer. Fix this by removing the unnneded __user in the cast. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
