mtd: fix different address space noise
In mtd_ioctl MEMGETREGIONINFO the region_user_info pointer ur is cast in __kernel space. This produces a number of sparse warnings like: warning: cast removes address space of expression warning: incorrect type in initializer (different address spaces) expected unsigned int const [noderef] <asn:1>*register __p got unsigned int *<noident> Since argp is already a void __user * just use it dirrectly without the cast and make ur a __user *.
