MIPS: Fix sparse warning in incompatiable argument type of clear_user.
The type of the second argument of access_ok should be (void __user *). The unnecessary conversion of the clear_user address argument was causing sparse to emit warnings on the __chk_user_ptr check. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
